BISCO® HT-870 soft silicone sponge is a top-tier material for sealing outdoor enclosures, providing cushioning and vibration isolation and protecting electronics from heat and shock. It has exceptional memory and low stress relaxation, which can significantly cut down on maintenance costs caused by gaskets failing due to compression set and softening. The extra softness of this material allow designers to use less force when sealing enclosures, whilst still ensuring devices are protected from environmental factors.
