What is Expanded 4x8 pvc foam board?
Expanded PVC foam board, also known as expanded polyvinyl chloride (PVC), is a lightweight, rigid form of expanded foam polyvinyl chloride. It is commonly used for commercial purposes like digital and screen printing, laminating, vinyl lettering, signage, and more. Eco-friendly and non-toxic expanded PVC sheets provide strength, durability, and flame and chemical resistance while remaining easy to cut and shape.

How is Expanded PVC Foam Board Made?

PVC foam is also lightweight, meaning it can be transported more easily than alternatives like glass, wood, or metal. It can also be an affordable option for those who want to provide corrosion and flame resistance.

The Applications for Expanded PVC Foam Boards
Because of its strength and durability, expanded PVC foam boards are a good alternative to similar materials like polycarbonate plastic that may be more prone to scratching. In addition, their resistance to chemical damage makes them ideal compared to other plastics, like acrylic for example, that may be damaged when using powerful cleaners.

Perhaps the most common use for expanded PVC foam boards is signage–specifically for outdoor usage where durability against corrosion is crucial. When business owners need a sign that can stand the test of time outside in the elements, they often turn to expanded PVC foam boards.
