Description

BISCO BF-1000 Extra Soft Cellular Silicone is a highly flame resistant material, ideal for sealing outdoor enclosures, protecting electronics from shock and heat and providing cushioning and vibration isolation. BF-1000 silicone’s excellent memory and low stress relaxation 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. This material offers superior vibration isolation in electronic components and transportation vehicles. BF-1000 is also ideal for use in environmental seals to protect against penetration of dust, moisture, air or light within outdoor enclosures such as lighting fixtures, HVAC units and electronic cabinets.
