Ensinger PEI
Rogers Corporation Bisco™ HT-800 Cellular Silicone Foam
Categories: Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE); Silicone; Silicone Foam

Material Notes: Medium grade silicon sponge. UL recognized for flame retardance and gasketing.

Applications: HID (High Intensity Discharge) lighting fixture gaskets, Battery cushion in hand-held electronic products, Seals in equipment access panels, Electrical and electronic enclosure gaskets, Solder gun insulation pads for work stations

Gasketing and sealing rating is JMLU-2 (Listed) per UL 157. No UV degradation per SAE J-1960. Ozone effect rating is 0 (no cracks) per ASTM D-1171. No staining per ASTM D-925(A). Passes AMS-3568 corrosion resistance. Passes SMP-800-C & BSS toxic gas emission rating. Passes hot flex at 230°C (446°F) per ASTM D-573.

General BISCO™ silicone information: BISCO™ Cellular Silicones are used as sealing cushioning, vibration isolation, insulation, and thermal management gaskets. Their resistance to environmental extremes, mechanical resilience, and safety features lead to their use in transportation equipment, communications and electrical enclosures, electronic products and components, industrial machinery, and appliances.
