BISCO® Cellular Silicones

<<Back to Previous Page

BISCO® Cellular Silicones are ideal for sealing, cushioning, vibration isolation, and insulation. Their resistance to environmental extremes, mechanical resilience and safety features make them perfectly suited for critical applications in transportation equipment, communications and electrical enclosures, electronic products and components, industrial machinery and appliances. BISCO Silicones also offer superb flame resistance and fire protection. Made in a wide range from ultra soft to extra firm, BISCO products serve as high-tech silicone sponges—with the enhanced sealing capabilities of traditional sponge rubber, but lighter in weight.

BISCO Silicones are the reliable choice for cushioning in solar panel constructions and in battery pad separators in hybrid electric vehicle design.
