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.

KT board is a kind of plate-like material made of polystyrene. The PS material particles are foamed into a board core and pressed by surface coating. KT board is light, not easy to deteriorate,and convenient for subsequent cutting and processing. It is widely used in advertising display, architectural decoration, cultural publicity walls,and packaging. The traditional KT board adopts film coating and board coating process, which has high labor and time cost. The difference is that UV flatbed printer brings different production methods to KT board processing.

At the earliest stage, KT board was divided into hot board and cold board. Now it is generally divided into PS film surface KT board, paper surface KT board, and PVC film surface cold-pressed KT board. KT board is widely used in indoor and outdoor publicity. Besides exhibitions, it is also applied in the construction and home decoration industry, such as KT board decorative painting. UV flatbed printer is a fantastic tool for printing decorative pictures, which is also suitable for KT board printing.

UV flatbed printers can print patterns directly on KT board. They save many traditional processes and significantly shorten the production time. They are especially suitable for small orders requiring changeable pictures and texts and can quickly respond to customer needs. In addition, the UV printer with a Ricoh nozzle and white color varnish scheme can also achieve oil painting like a three-dimensional relief effect.

For KT board printing, besides photo mounting and direct printing by UV flatbed printer, there are also devices with dual characteristics of UV curing and photo, such as “Mr. board”, which can also reach a printing speed of more than 40 square meters per hour. Of course, the needs of customers are always different. For advertising processing users requiring higher printing speed and printing needs of multiple materials and shapes, UV printers may have more advantages in versatility and capacity improvement.

The UV printing solution of KT board is to print patterns directly on KT board through UV flatbed printer. Through UV flatbed printer, processors can complete both large orders and small orders quickly. For users with small batch orders, delivery on the same day can be realized.

KT board UV flatbed printer adopts G5 nozzle, which can print 3D relief effect through the color configuration of color + white + varnish.

As one of the primary materials of the current media, KT board is suitable for medium and short-term advertising production with high-quality requirements and will not be deformed when used as poster board, writing board, promotion display board, etc. The solution of KT board UV printer not only brings different production modes for KT board advertising production but also gives advertising manufacturers a  new choice.

Structural components of both

Expanded Polystyrene foam board, also known as foam board and EPS board, is a white object heated and molded by heating polystyrene beads containing volatile liquid foaming agents after heating.

Extruded Polystyrene (XPS) Foam Board(KT board) is a new type of material formed by foaming chemical particles into board core and laminating on the surface. The main component also contains polystyrene. Common production processes can be divided into cold lamination and hot lamination. The products produced by these two different processes are called cold laminated board and hot laminated board. The popular colors of KT board core are white and black. In fact, they also have red, blue, yellow, green, and other colors.

Advantages of both

  •  Expanded polystyrene (EPS)foam board

The Expanded polystyrene (EPS)foam board has the advantages of low density, high recovery rate, and independent bubble structure. Secondly, the surface water absorption is low, and the anti-permeability is good. And acid, alkali, salt, oil, and other organic solvent corrosion resistance, excellent aging resistance. Furthermore, it does not flow at high temperatures and does not crack at low temperatures.

1. Protect the main structure of the building and extend the service life of the building. External insulation is to place the insulation layer outside the structure, which reduces the stress caused by structural deformation caused by temperature change, and reduces the corrosion of harmful substances in the air and ultraviolet rays to the structure.

2. Effectively eliminate the “thermal bridge.” In the past, internal insulation was used, “thermal bridge” was difficult to avoid, while external insulation effectively prevented the generation of thermal bridge and condensation.

3. The moisture temperature of the wall can be improved. Generally, the steam insulation layer is required for the internal insulation, while the temperature permeability of the external insulation material is much stronger than that of the main structure. Generally, condensation will not occur inside the wall. The temperature of the whole wall body of the structural layer is increased, which further enhances the thermal insulation performance of the wall.

4. It is conducive to the stability of room temperature. The external wall external insulation is adopted. Because the structural layer with large heat storage capacity of the wall is inside the wall, it is conducive to the stability of room temperature.

5. Increase the use area of the house. It can avoid the damage of secondary decoration to the insulation layer.

  • Extruded Polystyrene (XPS) Foam Board /(KT board)

1. The bubbling of hot laminated foam board is mainly caused by short ripening periods and too thin laminate film. The bubbling of cold laminated foam board is usually caused by poor gluing or too long direct sunlight exposure during production.

2. Price comparison: the low price of hot laminated foam board is mainly due to the short production period, less material, and large production capacity, while the cold laminated foam board is just the opposite.

3. There are many kinds of surfaces on KT board, such as PS surface, paper surface, and back glue surface.

4. KT boards are mostly used in indoor advertising. The general requirement for boards is to ensure no blistering and deformation.

Application fields of both

Expanded polystyrene (EPS)foam board is mainly used for building walls, roof insulation, composite board insulation, cold storage, air conditioning, vehicle, ship insulation, floor heating, decoration, and carving.

Extruded Polystyrene (XPS) Foam Board (KT board)

 is mainly used in the advertising industry, logo industry, architectural decoration industry, culture, art and packaging industry, printing industry,  and cosplay props.

Although Expanded polystyrene (EPS)foam board and Extruded Polystyrene (XPS) Foam Board (KT board) are made of expandable polystyrene beads, they also have different structures due to different processes. Before use, we must understand the difference between the two to avoid confusion.
