BISCO HT-820 Firm Silicone Foam
BISCO HT-820 Firm Cellular Silicone Foam provides enhanced durability and sealing in a wide range of environmental conditions and applications.
BISCO HT-820 Firm Cellular Silicone Foam is a firm-grade silicone foam that provides enhanced durability and sealing.
HT-820 foam offers a higher tear and tensile strength than our lighter-grade foams.
This material is designed for use in enclosures requiring a more durable, high-closure force gasket.
HT-820 foam is ideal for sealing and protecting outdoor communication, lighting, and electronic enclosures from small dust particles, wind-driven rain, and fire.
