1. PVC resin powder
    It is the primary raw material, foaming base material, producing PVC foamed sheet generally adopts Model SG-8 PVC resin. When processing, the gelatinization speed is fast, the processing temperature is relatively low, the product quality is stable, and the density is easy to control. In order to improve product quality and strictly control the fluctuation of product density and thickness, SG-8 PVC resin is often used in the production of free foam and Celuka foam PVC sheets.
  2. PVC stabilizer
    In order to fully plasticize the material during the process of PVC foam board, the material is often at high temperatures. In addition, the foaming agent also produces decomposition heat in the process of decomposition. These factors require that the stabilizer have sufficient thermal stability to ensure the quality of products and long-term stable production.
  3. Foaming regulator
    It is made of methyl methacrylate, ethyl acrylate, butyl acrylate, and styrene. Its molecular structure is a core-shell structure. As a processing aid in the formulation system, it can effectively reduce the plasticizing temperature, promote the plasticizing effect, improve the plasticizing efficiency, improve the melt strength, reduce the melt pulsation, prevent the melt fracture, and significantly improve the surface smoothness of products. The selection principle of the foaming regulator includes plasticizing speed, melt strength, and melt fluidity. Because of different process conditions, foaming regulator models should be selected according to the various product property characteristics, such as foamed sheet, thick foamed sheet, thin foamed sheet, wood plastic foamed sheet, etc. They can ensure the uniformity of the melt and good board surface quality. Besides that, we need to choose good quality internal and external lubricants and add enough heat stabilizers to the formula.
  4. Foaming agent
    The foaming agent is the material that makes the object material into a cell structure. It can be divided into the chemical foaming agent, physical foaming agent, and surfactant. It is mainly used to control the density and measurement of PVC foaming boards.
  5. Filler
    In the formula system, the general dosage of light calcium carbonate is 10 ~ 40 phr. Filler can not only be used as a foaming nucleating agent but also reduce the material cost. However, excessive dosage of light calcium carbonate will make the cell uniformity worse, then affect the appearance and product quality. It finally makes the product density difficult to control, increases the total cost, and reduces the product hardness.
  6. Pigment
    It is used for coloring the board, mainly in white, red, yellow, blue, green, black, gray, etc.

PVC foam board can be used as furniture board, and its development trend is more and more popular in the world.

A wide range of laminated PVC foam board materials can be used for both modular furniture and kitchen cabinet production.

PVC board is used in kitchen decoration

PVC board has excellent chemical stability, corrosion resistance, high hardness, high strength, anti-ultraviolet (anti-ageing), fire retardant (with self-extinguishing), reliable insulation performance, smooth surface, tiny water absorption rate, no deformation, easy processing and other characteristics.

PVC foam board has a lightweight, smooth surface, good visual effect for furniture, and the strength of the material is improved after foaming, which can replace the wood board and extend service life. PVC foam board is generally used as the substrate material of furniture board. Different kinds of decorative materials are laminated on the substrate surface via PUR hot-melt adhesive machine, such as PVC decorative film, PET film, HPL, aluminum sheet, PETG film, PP film, etc. In addition, it is necessary to use an edge banding strip to seal the board edge after cutting. The finished board adds more durability, diversity and aesthetic result after lamination.

PVC board is used in decoration

The density of PVC board used in the furniture is not less than 0.45 g/cm3, and the ideal standard density is 0.50 g/cm3. Meanwhile, the 0.60 g/cm3 density of PVC board is also used in famous furniture brands. Using the 0.60 g/cm3 density coextrusion PVC foam board to make PVC bathroom cabinets, and because of its waterproof advantages, the product’s durability can reach more than 20 years.

In the past, many furniture factories chose PVC Cekuka foam board to make PVC bathroom cabinets. The reason is that the cost of PVC co-extruded board is higher than that of PVC Celuka board. But now, the production technology and formula have become mature. Some physical performance is much better than that of PVC Celuka Board. PVC Coextrusion Board can be a high-end product of PVC foam board.

I believe many people are familiar with PVC foam board and Foamboard. They are very common exhibition materials. The most obvious contrast is that PVC is harder than Foamboard. But which of the two kinds of printing boards will be easier to use? Next, Skyline Composites will analyze the two kinds of materials from various aspects, including characteristics, price, purpose, usage and application, so that you can use the two kinds of advertising material properly.

PVC Foam Board and Foamboard Material Introduction

Foamboard (also known as foam board) is made of polystyrene (PS) foam. The foamed core will be pressed into a sheet, and a thin layer of PVC film will be laminated on the foam core, and after that, it forms into our common Foamboard. Foamboard is light in weight and low in price. However, due to the soft substrate core, it is easy to be deformed due to pressure, so it is not suitable for making complex models, and it needs to be used with great care.
PVC board is made of PVC, but it foams in the heart, resulting in a density 3-4 times higher than that of Foamboard. Due to the increase of density, the hardness of the PVC board is also improved. The PVC board will not be deformed by squeezing.

Application examples of Foamboard and PVC

  1. Backdrop
    Use: 5mm Foamboard
    Since most of the activity backdrops are used indoors for a short time, and the Foamboard is light and easy to install, it is recommended to use the Foamboard.
    For example, you can use Foamboard to make the backdrop for short-term outdoor activities, but it is more suitable to use PVC board for long-term outdoor activities.
  2. Props (Props check, Facebook Like props)
    Use: 5mm Foamboard
    Props are disposable props, which are mainly used for taking photos in activities, such as the common props check for the charity dinner. After the end of the dinner, the mission is completed.
    In addition, you can print different shapes of die-cut props as required.
  3. Instagram / Facebook Frame
    Use: 5mm Foamboard / PVC board
    IG / FB frame is a popular photo prop of Foamboard in recent years. Two or three people take photos with the frame, such as in the post. Skyline composites suggest that you can make the frames with the fixed position so that you don’t have to hold the frame to take photos, and participants can put more posts. If it is made for the company, PVC board can be used so that it can be reused.
  4. Image Cutout
    Use: 5mm PVC board
    It is recommended to use the PVC board to make cutout cards because the Foamboard is too easy to deform, and it will be damaged if it is pressed down by hand. And as long time use, PVC board is absolutely reliable. Of course, it’s OK to use Foamboard, but the damage risk can be very high.
  5. Exhibition booth
    Use: 5mm Foamboard
    In an exhibition, the material used at the booth is the Foamboard, which is generally divided into H-shaped (three sides with Foamboard) and L-shaped (two sides with Foamboard). The reason why we use Foamboard is that it is short-term and low cost.
  6. Promotion desk
    Use: 5mm Paper Foamboard / PVC
    The best promotion combination is assembled with an aluminum frame and printed board. Whether it should use the paper board or PVC depends on if the design is disposable or long-term. The picture on the promotion desk can be changed by itself, but it is time-consuming.
  7. A-Frame / H-frame
    Use: 5mm Paper Foamboard / PVC
    Both A-frame and H-frame are indicator boards, which are usually used to display promotion information or the latest news. Two kinds of the printed board are replaceable. You can order the printed board according to the requirements of the frame, and the general thickness is 3-5mm. PVC can be used for a long time, but you can use paper foam board if you want to save money.
  8. Advertising stand
    Use: 5mm Paper Foamboard / PVC board
    The stand is made by adding a paper backboard on the non-printed side of the Foamboard / PVC board so that the drawing board can stand on the stage. Commonly used sizes are A4 and A5. You can also customize different sizes and shapes.

People are more and more concerned about the safety of the products they choose to buy and use in their daily life or business projects. There are many options to protect belongings and buildings when selecting a product, such as Flame-Resistant & Flame-Retardant, Fire-Resistant & Fire-Retardant. We can Flame and fire interchangeably. The terms Flame Resistant and Fire Retardant are both commonly referred to as FR). But Resistant and Retardant describe two different product features.

In this article, we will guide you to make clear the main differences between fire-retardant and fire-resistant.

The main difference between fire-retardant materials and fire-resistant materials is how the material melts when exposed to fire and how long the material self-extinguishes.

Resistant is recognized as a material that is inherently resistant to catching fire (self-extinguishing) and does not melt or drip when exposed directly to extreme heat. When they catch fire if exposed directly to a flame, Flame-resistant materials are not likely to catch fire just from being near the fire. In the meantime, a fire-resistant material catch fire, it will have a hard time staying lit. These materials will choke the fire, causing it to extinguish.

Retardant is defined as a material that has been chemically treated to self-extinguish. The treated material can self-extinguish and does not melt or drip, therefore, cause less damage to humans. In a word, fire-retardant materials have been chemically treated to slow ignition, burning, or actually self-extinguish when exposed to an open flame. Original material needs chemically treated to retard the spread of flame.

PVC foam board and WPC foam board are water-proof, fire-resistant, recyclable and lightweight expanded PVC foam material, and suitable for indoor and outdoor application.

Foam board is one of the most popular and versatile materials in today’s advertising industry. This material provides affordable and high-quality solutions for individuals and businesses in all sectors. It features a short application life of around 6-12 months, recyclable properties, and highly competitive costs. Foam Board is considered as an ideal material for temporary projects with tight budgets that don’t want to sacrifice quality. Foam Board has a variety of applications, including:

  • Informative Displays
  • Trade Show Advertising
  • Promotional Events
  • POP Signage
  • Display Systems

At Skyline Composites, We produce dozens of foam board product models that supply a wide range of creative and live events, trade shows, photo, stage applications. We always recommend foam board printing and photo mounting to our customers when guaranteeing them optimum results. Here, we would like to introduce some of the main projects which are the most suitable solutions to the foam board printing applications.

UV Flatbed Printing for Business

UV Flatbed printing is a form of digital printing that uses ultra-violet lights to dry or cure ink as it is printed. As the printer distributes ink on the surface of substrate material, specially designed UV lights follow close behind, curing or drying the ink instantly. Because of the outstanding smooth surface and versatility of this material, foam board is used for high-quality photo printing in photography, and in the office for meeting presentations. Another good example of this is indoor art projects, which demand high-quality output images and an extraordinary finish. Individuals and companies choose foam board UV printing when they want to create affordable yet vibrant artworks, mainly aimed to decorate interior spaces where they can be appreciated in detail.

Making a School Fun

Printing on foam board allows small companies and schools to make fantastic visual impact on viewers. Pop-up displays are an excellent example of this, often used by businesses in point-of-sale advertising to increase results and in school projects and exhibitions. Besides the high-quality images that can be printed on foam board, we must also consider its lightweight, allowing easy manipulation and installation. For this same reason, school activities or exhibitions always use it, letting kids join the games and create their artwork via using this material while keeping them safe at all times. In the meantime, foam board may be the lightest advertising material, allowing its printing to be installed on ceilings by using strings, ropes, or 3M tape. Foam board is paramount for schools or small businesses with limited space.

Trade Show Displays

Big or small companies cut costs by strategically planning to cater to the expected turnout of a given show, the size of your booth, and your primary sales objectives. For some events, they will want to take up as much visual real estate as possible and pull out all the stops to attract the most attention. They need to look for cost-effective, efficient, good-looking advertising materials when they showcase at trade fairs under a tight budget. Product durability isn’t truly a key factor since people will likely use them once or twice during a short period of their trade show displays. Foam board is one kind of easy-process advertising material. It can be sculpted by CNC cutter, framed on easels and also be hung with 3M double-sided Velcro tape. It’s a fact that foam core board doesn’t last for a long time, but its affordability allows wide ranges of applications, and it’s lightweight enough to save the work on transportation and installation process. The assembling and disassembling work will also save more manual labor. Foam board is exciting stuff.

Restaurant Business Promotion

What is today’s best recommendation? Do you have any hot new products that have been just landed? At least, you need to display your information to your customers or passersby. Some custom printed advertisements will get folks interested in your products. Visual signage with some message is the voice of your restaurant or brand. One modern use of foam board is at restaurants. Besides point-of-sale advertising, restaurants use foam core printing for their menu boards and POP-Up displays. Poster board printing’s cost efficiency and versatile is the reason we see this rising trend.

UV printing is absolutely the most popular printing trend in today’s advertising industry. It allows printing on a wide selection of substrates, such as PVC foam board, foam board, cardboard, wood, acrylic, aluminum, etc. Its advantages include environment-friendly, easy to process, customizable digital printing, competitive cost, high printing resolution. Here is some little details to get to know more about UV printing.

UV Printing Overview

UV printing is a kind of digital printing that uses ultra-violet lights to dry or cure ink when it is printed. As the printer distributes ink on the surface of a substrate, specially designed UV lights follow close behind, curing or drying the ink instantly. As the UV lights cure printed ink immediately, the dots of wet ink do not get a chance to spread out once printed, resulting in much finer detail. More over, UV-cured inks are weather-resistant and offer increased resistance to fading. This curing process is more environmentally friendly as it produces few VOC’s, odor, and heat. UV curing also allows the flatbed printer to be used with unconventional materials like acrylic or aluminum.

Flatbed Printer Ink

UV flatbed printer works like an inkjet printer. The main difference of a UV flatbed printer is:

  • The type of ink used – UV-curable ink
  • And how the ink is applied to the substrate – the surface being directly printed upon

UV flatbed printing devices apply UV ink to a substrate, and the ink must be cured quickly to create a permanent image.

UV Ink Curing Process

When a printing substrate pass the flatbed printer, the UV ink is applied, and almost immediately, the ink is subjected to ultra-violet light. This light instantly cures or dries the ink to the substrate surface.

Because the UV ink has no time to spread out or bleed into the substrate, UV flatbed printing produces amazingly accurate color details with very little image loss.
The UV ink hardens to a solid finish and is resistant to fading and weathering, depending on the surface being printed upon. Flatbed printing process is more environmentally friendly than some other printing methods.

Flexibility of a UV Flatbed Printing

Flatbed printer machine is capable of printing on a variety of unique substances, both smooth and rough, including foam board, wood, aluminum, acrylic, coroplast, and other different types of substrates.

Flatbed printer head can raise or lower and allow for printing on very thin surfaces, such as promotional pieces for trade shows, or most often, on thick surfaces, such as office doors.

People are often confused by some of the names and terms of the rigid substrate in the signage industry. Two of the more common rigid substrates utilized in signage are foam board and PVC foam board. But, there are some misconceptions and misunderstandings about them.
Here, we’ll try to clarify some of their information that you might have puzzled over, and explain some of the primary advantages and disadvantages to each.

Foam Board : Interior Solution

Foam board is used for a wide range of applications, including interior signage, point-of-purchase displays, posters, presentations, and in model settings.

Typically consisting of an extruded polystyrene foam core with a paper liner on both sides, foam board is very lightweight but relatively strong. It can be propped against an easel without any support. It is a sturdy alternative to standard posterboard.

This cost effective substrate is very suitable for digital direct printing, whether using UV inks, eco-solvent inks, solvent inks, aqueous inks. And it’s easy to cut with a razor-type knife or a digital cutting machine.

However, because of foam board’s exterior paper liner, it should mainly be used only for indoor signage – it won’t perform well to rain or other inclement weather. Plus, because it’s lightweight, it requires extra anchoring if utilized outdoors. Foam board won’t withstand a lot of physical damage – it’s relatively easy to bend or pierced with thumbtacks, so you should be careful in how and where you display it.

Because foam board is lightweight, it’s easily displayed. If you don’t wish to prop it on a freestanding easel, you’ll add an easel back within the production process. Other alternatives include hook-and-loop patches like Velcro, or adhesives like 3M Command Strips.

Another advantage of foam board being lightweight: It’s convenient to transportation – which may are available handy if you’re shipping signage to events, conferences, trade shows, etc.
And it’s economical – so if you need a large quantity, you won’t spend a lot of money.

Here at Skyline Composites, our foam boards comprise an expanded polystyrene core with paper faces or HIPS film faces. We offer it in 5mm (3/16-inch) and 10mm(3/8-inch) thicknesses, and in standard size 48 x 96 inches.

PVC Foam Board: Interior and Exterior Solution

If you would like a sturdier alternative to foam board – and one which will perform well in outdoor and indoor – you would like look no further than PVC foam board. Sometimes called expanded PVC board (foamed PVC, Sintra board), this substrate provides better sturdiness.

PVC foam board comes in a wide range of thickness, density and color. It is commonly utilized in the sign and graphic industries because it is lightweight, printable (digital and screen), has excellent screw retention, and is in a position to be die-cut. Foam PVC has superior UV performance and fire resistance which allows it to be used for both indoor and outdoor applications.

PVC foam board is durable – it has good resistance to dents, scratches. It also holds up quite well under extreme weather. PVC foam board is resistant to chemicals, which comes in handy for simple cleaning. For outdoor applications, thicker is better.

Like foam board, PVC foam board are often printed onto directly with digital print technologies, including UV inks, eco-solvent inks, solvent inks, aqueous inks, etc. And it’s very machinable: PVC foam board are often fabricated into custom shapes with a blade, saw, router, or a digital cutting system.

Some additional notes on PVC foam board:

  • You can use PVC foam board outdoors and indoors, and it works well for temporary as well as permanent signage.
  • Bend, don’t crack: You can bend PVC foam board. It’s easy to process, but it doesn’t crack easily.
  • Avoid extreme temperatures: PVC’s core gets weaker in extremely hot or cold temps. It can warp if it gets too hot – placed in a hot space with no ventilation, for instance. And it can get weaker if exposed to very cold temperatures for an extended period.
  • Display options: Unlike foam board,you are able to drill holes in PVC foam board, which allows for displaying with bungee, rope, chain, or other.
  • Eco-friendly: PVC foam board is 100%recyclable, making it a “eco-friendly” choice.

Skyline Composites offers a closed-cell, expanded PVC that’s available in 3-20mm thickness with different density and colours.


Foam board is a perfect solution for temporary display or signage which will only be displayed indoors. It may not be the foremost durable of signage, but it typically doesn’t need to be when displayed within the proper environments. PVC foam board performs great both outdoors and indoors, and it can resist more in the way of physical damage – whether that might come from humans or nature. Because both substrates are very suitable to digital printing, each will nicely showcase your graphics and message.

If you have any questions about either foam board or PVC Foam Board, Please don’t hesitate to contact our sales department.

The ongoing COVID-19 pandemic has not only expanded over the world, but it has also been our major topic of discussion each day. At the same time, the pandemic has had a drastically negative impact on most businesses.

According to our reported sales volume data in 2020, a revenue decrease due to the pandemic is only 10%. However, the challenges posed by the pandemic have formed out creativity and resourcefulness. Skyline Composites overwhelmingly feel the pivots it has made over the past year will have a long-term positive impact, empowering businesses to be more agile and nimble in the future.

It’s a surprise if your company or industry hasn’t been affected by the pandemic, with employees needing to work overtime or hike up production to meet spikes in demand for products or services. Skyline Composites is a good example.

As a diversified plastic products supplier, we have been focusing on domestic and international markets with more reasonable and competitive market pricing. With an increased demand for public health promotion and governmental culture propaganda throughout China and for advertising projects, we have seen an increased demand for our products at the beginning of 2021.

We have received a record number of orders of plastic sheets since the virus first occurred in China, meaning that we have received increased demand and had our best-selling products temporarily out of stock. With this high demand, it has been a challenge for us that we have been able to achieve. Whilst stock levels depleted quicker than we ever anticipated, we extended delivery times to provide more time to fulfill orders in our production and warehouse. During March, we even made the decision to temporarily pause our marketing efforts to reduce the flow of orders to allow us to keep up with the workflow. But overseas orders are our priority to make the delivery.

PVC foam boards and PS foam boards are not only found in supermarkets but also found in many supermarkets, retail stores, pubs, restaurants and cafes, schools, hospitals, nursing homes, etc.
