3M Polyimide 8997 and 8998

BISCO® HT-820

Rogers BISCO® HT-820 Silicone Foam is a firm-density, open-cell silicone foam engineered for applications requiring high closure force, rugged sealing, and mechanical durability. With enhanced tear and tensile strength, HT-820 offers sponge-like performance with the longevity and flame resistance of cellular silicone. Its ability to resist UV, ozone, and extreme temperatures makes it ideal for demanding gasketing, sealing, and thermal barrier applications in transportation, industrial, and electronics markets.

Applications include: Active safety, cold supply chains, gap filling, gasketing and sealing, shock absorption, and vibration management.
