BISCO HT 820 Strong silicone foam
Bisco HT-820 provides increased durability and tightness in a wide range of environmental conditions and applications. BISCO HT-820 Firm Cellular Silicone is a hard silicone foam that provides increased durability and tightness. HT-820 foam provides higher tear and tensile strength than our lighter foams. This material is intended for use in housings requiring a more durable seal with high closing force. HT-820 foam is ideal for sealing and protecting outdoor communications, lighting and electronic housings against fine dust particles, wind and fire.
