HT-840

HT-840 is a very firm grade silicone foam that offers the enchanced sealing capabilities of a sponge rubber.  It is used to seal and protect various outdoor communication, lighting, and electronic enclosures from small dust particles, wind driven rain, and fire.  It offers a higher tear and tensile strength than our lighter grade foams.
