BF1000 Silicone foam is soft cellular Silicone foam material and is supplied in white as standard. BF1000 Silicone foam sheeting is an ideal choice for sealing applications due to its compressibility, softness, and durability. It has excellent memory and low stress relaxation, and the softness of the material means that less force is needed to seal.

Due to its excellent resistance to UV light and ozone, combined with an excellent low and high temperature range, BF1000 Silicone is commonly used for outdoor applications, such as sealing enclosures to protect from heat and the elements, as well protecting electronics from shock and providing cushioning and vibration for a wide variety of applications.

BF1000 Silicone foam sheeting is Fire Safe – approved to BS6853, EN45545 and UL94 approved to V-0 and HF-1.
