Silicone Foam

BISCO® HT-840 (Extra Firm)

Rogers BISCO® HT-840 Extra Firm Cellular Silicone provides enhanced durability with the excellent sealing properties of sponge rubber. BISCO HT-840 Extra Firm Cellular Silicone is a very firm grade silicone foam that offers superior sealing capabilities. HT-840 silicone provides a higher tear and tensile strength than our lighter grade foams. HT-840 silicone is designed for use in enclosures requiring a more durable, high closure force gasket. This material is also ideal for use in press pads requiring greater conformability and even pressure distribution at high temperatures. HT-840 silicone is a great choice for sealing and protecting outdoor communication, lighting and electronic enclosures from small dust particles, wind-driven rain and fire.
