At present, most advertising production uses acrylic and PVC materials, which are recommended every time you go to advertising companies.

In fact, these two are the most commonly used primary materials. They are mainly used for mounting pictures on the surface and engraving for modeling.

Engraving mainly involves PVC and foam boards. PVC specifically makes characters and models, and foam board mostly makes some indoor signs, custom shapes, display panels, etc.

So what is the difference between foam board and PVC foam board?

KT board

1. Different materials:

PVC is a plastic material, and the foam board is a foam material.

PVC foam board: the main component is polyvinyl chloride. Foam board: mainly composed of polystyrene.

The foam board material is a foam board, the inner foam is foaming, and the outer layer of the sheet is very light, and the price is low.

Because the core is too soft (the foam is flat), it is not suitable to make complex models and shapes, so it is not suitable for complex sculptures.

Of course, you can do it carefully with a manual knife, but the effect is obvious. The result is not as good as that of PVC foam board.

 The Foam board is not sunscreen and waterproof. In case of exposure to the sun and rain, the surface will blister and deform, which will affect the image surface quality.

 Foam board is easy to cut and install, but the surface is relatively fragile, and it is easy to leave traces when it is accidentally touched.

PVC is foamed with plastic inside and PVC veneer outside. Due to its high density, the weight is 3-4 times heavier than foam board. Of course, the price is also 3-4 times higher,

The hardness is relatively high. A good PVC foam board can’t be pinched with your fingers. It’s terrific to use this to make complex models and fine carving.

Secondly, PVC is sunscreen and waterproof and will not deform in case of exposure and rain.

PVC also has the characteristics of fire and heat resistance. It is mainly used to replace wood as a fireproof material.

The surface of the PVC foam sheet is very smooth, has high hardness, and not easy to scratch.

2. Different use-values:

PVC foam board is more widely used and has better material characteristics. PVC foam board is relatively rigid and much heavier than foam board. Due to the high density of PVC, the weight is 3-4 times heavier than foam board. Of course, the price is also 3-4 times higher. Some PVC prices are even more than + 5-10 times higher than foam board.

3. Different application ranges:

Foam board is mainly used for indoor short-term advertising displays. It works as a backboard for stickers, PP paper with mounted and printed pictures.

The main reason is that the material of the foam board is light and easy to install.

PVC is generally used for outdoor medium and long-term advertising display.

 Foam board is mainly used in the indoor sign industry, DIY production (especially aircraft model production), and cosplay props.

PVC is mainly used for outdoor billboards, site signs, etc. It can also be used indoors, such as signs and placards in harsh environments such as workshops and plants.

Other uses: PVC is more used for laser engraving characters and various cultural walls and background walls, mainly for long-term use.

Foam board is used for various special-shaped labels, hands-up cards, and supermarket personality cards, primarily for short-term display.

How to select:

The scratch resistance and durability of PVC foam boards are better than that of foam boards. However, the cost of PVC foam board is much higher than that of foam board. Therefore, which one to choose depends on the cost control, use scenario, and time limit.

4. Summary:

  1. PVC is a plastic material, and foam board is a foam material.
  2. PVC material is rigid and suitable for machine engraving. Foam board material is brittle and can not stand machine engraving, but it is ideal for manual engraving.
  3. Both PVC board and foam board can be used to mount the picture. PVC board is used outdoors, foam board is used indoors, PVC board can be used for a long time, and foam board is used for a short time.
  4. PVC board has high hardness and is not easy to cut by hand. Foam board has low hardness and can be cut by hand.
  5. PVC has strong scratch resistance, and the foam board is fragile, which is easy to produce scratches.
  6. PVC has strong durability and is suitable for long-term use. Foam board has weak durability and is ideal for medium and short-term use. (within 1-2 years).
  7. PVC board is suitable for outdoor use, and Foam board is ideal for indoor use.
  8. PVC is heavy and needs to be reinforced. Foam is light and easy to install.
  9. The price of PVC is 3-4 times the price of PVC board (also 3-4 times the weight). Better PVC is more than 5-10 times.
  10. PVC also has the characteristics of fire and heat resistance. It can replace wood and be used as a fireproof material.
  11. PVC is more used for CNC engraving characters and various cultural walls and background walls, which are mostly used for a long time.
  12. Foam board is used for various special-shaped labels, hands-up cards, and supermarket personality cards, primarily for short-term display. Foam board is not weatherproof and waterproof. In case of exposure to the sun and rain, the surface will blister and deform, which will affect the image surface quality. PVC board is weather-resistant and waterproof and will not twist in case of exposure and rain.

Foamboard, also known as foam core, is one of the most cost-effective and backing materials used in mounting art. It is made of polystyrene foam, covered with paper or plastic on both sides, making PS foam the core of the sandwich. This material is usually white, but the manufacturer also offers black or other colors. Product thickness is generally 1 / 8 or 3 / 16 inch (0.3 or 0.5 cm) thick. The normal size is 4x8ft.

Pins and pins can puncture the surface of the foam board. This material is light and robust. Foamboard is ideal for making large works of art or posters because it adds too little weight to the whole work. Its rigidity stabilizes paper art, but it is not the real archival material. Polystyrene foam will be decomposed over a long period, and the by-product of this decay may be acidic and accelerate the aging of its framed art.

Foam boards can be used as disposable bulletin boards. Foam panels can be purchased in large areas, making it the second-largest exhibition board for school projects and science exhibitions. By sticking the white artist tape to the connection on one side, three large boards can be hinged together to form a three-fold or triple display screen. Fabrics can be used in creative projects based on foam panels and can be perforated with pins or pins. Foam boards can make a good disposable bulletin board, which costs only a small part of the soft board. When there are too many pinholes on the surface to be reused, throw it away and buy a new board.

The surface of the foam board is smooth enough, and the dry-erase mark can also be used to make a temporary whiteboard. We can creat one piece of general indoor bulletin board/whiteboard via the easy-cutting by a razor. It accepts paint and felt tip marks, and the fabric can adhere to its surface. For these properties, foamed plastic boards have become the building materials chosen by modelers. If your promotion project needs a castle city model, or your action star pilot needs a space terminal, this material, a knife, paint, and glue can create background and props for your specific needs. People usually use Foam boards for model making.

Therefore, the foam board is widely applicable in advertising display and promotion, aircraft model, architectural decoration, culture and art, packaging, etc. In our daily life, we often use simple foam promotion boards, exhibition boards, corporate culture walls, or party-building walls to make foam panels.

  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.

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.
