BISCO® RS-800 Series Flame-Resistant Silicone Sponge

The BISCO RS-800 series is trusted in a variety of applications, for gasketing and gap filling, including electrical enclosures, lighting fixtures and transportation.

BISCO RS-800 products exhibit excellent flame resistance to UL94 V-0, a compression set of below 5%, as well as high tensile strength and elongation. These properties make BISCO RS-Series materials resilient, enabling them to outperform competitive materials in challenging environments where superior silicone performance is needed.

BISCO RS-Series materials are available in continuous roll form and four firmness grades — soft, medium, firm and very firm — to suit a wide range of applications. While the BISCO RS-800 series is a cellular silicone sponge alternative to BISCO HT-800, there are some differences between the two products. See sell sheets for a complete comparison of material properties.
