BISCO HT-870

Rogers BISCO HT-870 Soft Cellular Silicone is a firmer, denser version of our BF-1000 Silicone and offers the ability to seal and cushion within a wide range of applications.

BISCO HT-870

BISCO HT-870 Soft Cellular Silicone is ideal for sealing outdoor enclosures, protecting electronics from shock and heat, and providing cushioning and vibration isolation.

With excellent memory and low-stress relaxation, HT-870 silicone reduces maintenance costs from gasket failures caused by compression set and softening.

Its extra softness allows designers to use less force to seal enclosures while still protecting devices from the environment.
