Foam boards are composite materials with cardboard or plastic film as the two skins and expanded polystyrene plastic as the core. The core is highly expanded, containing about 90% air, which makes the board very lightweight. The two layers of cardboard give the board stiffness and support. Foam boards are used for printing, painting, mounting, and are also used for POP displays, exhibits, kiosks, sets, props, framing, and signage. PVC foam boards are a type of foam board made of polyvinyl chloride. They are highly waterproof and moisture resistant, making them ideal for outdoor use. They are also fire-retardant and self-extinguishing, achieving Class A or Class 1 fire ratings.

What You'll Learn
PVC foam board is made from polyvinyl chloride
PVC foam board, also known as PVC foam sheet, is a lightweight and versatile plastic material. It is composed of two rigid sheets enclosing an inner foam core. This core is made primarily of polyvinyl chloride (PVC) resin powder, which forms the main component, making up over 70% of the foam board by weight.
PVC resin imparts rigidity, weather resistance, and fire retardant properties to the foam board. It is combined with foaming agents, which create air pockets in the material, giving PVC foam boards their characteristic lightweight, smooth, and rigid structure. The foaming agents make up around 2-5% of the board's weight and aid in the expansion of the resin into a uniform closed-cell foam structure. Common foaming aids include azodicarbonamide and zinc compounds.
Activated light calcium carbonate is added to the PVC resin and foaming agents, making up 10-20% of the board's weight. This mineral filler enhances the foam density and improves dimensional stability. Additional additives in minute quantities, such as heat stabilizers, lubricants, and pigments, may also be included to optimize performance.
PVC foam board is known for its durability and ability to withstand harsh weather conditions. It is also lightweight and easy to work with, making it a popular choice for trade show booths, display cases, staging, event displays, and kiosks. In addition, PVC foam board is highly waterproof and moisture-resistant, with a very low water absorption rate of only 0.08%. This makes it ideal for outdoor use and humid environments, as it does not corrode or degrade when exposed to water.

PVC-free foam boards use polypropylene or polyethylene
Foam boards are composite materials with cardboard or plastic film as outer layers and expanded polystyrene plastic as the core. They are lightweight, easy to fabricate, and ideal for printing, painting, and mounting.
PVC foam boards, on the other hand, are made of polyvinyl chloride (PVC) resin combined with foaming agents. They are lightweight, sturdy, and suitable for interior or exterior applications where strength, durability, and design flexibility are required. They are also highly waterproof and moisture-resistant, making them ideal for outdoor use and humid environments.
PVC-free foam boards are made without polyvinyl chloride (PVC). Instead, they utilize polypropylene or a blend of polypropylene and polyethylene. These boards provide similar strength and durability as traditional PVC materials. They are ideal for projects where chemical leaching is a concern and are commonly used for exterior signage, model building, crafts, and marine/boat building.
PVC-free foam boards offer several advantages. Firstly, they address concerns related to chemical leaching, which is the unwanted transfer of chemicals from the board to its surroundings. This makes them suitable for projects where chemical leaching may pose environmental or health risks. Secondly, PVC-free foam boards provide comparable strength and durability to traditional PVC materials. This means that they can withstand wear and tear and provide long-lasting performance. Additionally, these boards have enhanced thermal insulation properties, making them suitable for applications where maintaining temperature control is important.
Overall, PVC-free foam boards made with polypropylene or polyethylene offer a sustainable and durable alternative to traditional PVC materials. They are ideal for a range of applications, from signage to model building, and provide superior thermal insulation. By eliminating PVC, these boards address environmental and health concerns related to chemical leaching, making them a more eco-friendly choice.

Foam board is a composite material with cardboard or plastic film skins
Foam board, also known as foam core board or KT board, is a composite material with cardboard or plastic film as the two outer layers or 'skins'. The core is made of expanded polystyrene plastic, which is highly porous, containing about 90% air. This makes the foam core very lightweight, but also soft and easy to crush with your fingers. The two layers of cardboard give the foam board stiffness and support.
Foam board is easy to fabricate and can be cut with a knife, making it ideal for printing, painting, mounting, and laminating. It is commonly used for the mounting of prints and photographs and as backing in picture frames. It can also be used for interior design and architectural models.
There are several grades of foam board available, including FOME-COR®, which is a popular graphic art board known for its performance. It is made of extruded polystyrene foam with clay-coated white or black paper facers. Another grade is GATORFOAM® EXTERIOR, which is made to weather all kinds of outdoor conditions. It consists of wood-fibre veneers bonded to an extruded polystyrene foam core with a weather-tolerant adhesive.
PVC foam board, on the other hand, is made of polyvinyl chloride (PVC) resin combined with foaming agents. It is a lightweight and versatile plastic material composed of two rigid sheets enclosing an inner foam core. PVC foam board is highly waterproof and moisture-resistant, making it suitable for outdoor use and humid environments. It also meets strict fire safety standards and is considered self-extinguishing.
There are several types of PVC foam boards, including PVC Celuka board, PVC co-extruded board, and PVC free foam board, each with its own unique properties and applications.
