Product Description

Product Description:

Polystyrene Foam Board (PS Foam Board) is a high-performance, lightweight and durable product, which is widely used in a variety of applications, such as construction, furniture, exhibition, insulation, signage, and advertising. It is made from expanded polystyrene (EPS) foam, which is strong and rigid, and has excellent impact resistance, smooth surface, and square edge. It also has good moisture resistance and fire rating of Class 1. Our custom foam board can be fabricated into a variety of shapes and sizes to meet your specific needs. So choose our PS Foam Sheet to create, protect, and display your ideas!


One advantage of PS foam board over other foam boards is its high resistance to moisture. Unlike other foam boards, PS foam board does not absorb moisture, making it ideal for use in high-humidity environments or outdoors.

PS foam board is commonly used in the signage industry for indoor and outdoor signs, as well as for trade show displays and exhibition stands. It is also used in the framing industry for mounting and framing artwork, photographs, and prints due to its lightweight and rigid nature. Additionally, it is used in the packaging industry for protecting fragile items during shipping.
