Rubber Sheet #5216728

SF expanded cellular silicone rubber has a partially closed cell structure and an integral surface skin with a fine fabric finish. It has high compressibility and resilience over a wide temperature range, making it an excellent material for gasketing applications. SF grades are suitable for long term continuous use from -60F (-50C) to 400F (204C) and for intermittent use from -80F (-62C) to 450F (232C).

SILICONE RUBBER SHEET
General CharacteristicsSilRubberSheet

Suitable for continuous operation at temperatures from -60F (-50C) to 400F (204C) and for intermittent use from -80F (-62C) to 450F (232C). Red iron-oxide formulations are suitable for continuous use up to 480F (250C). Depending on media and application useful life at temperatures up to 570F (300C) may be obtained. Chemically stable and suitable for use with many acids and alkalis. Resistant to ozone, UV and corona discharge. Electrically insulating with dielectric strength 500 Vmil. Inherently low flammability and low smoke. No harmful toxic or physiological effects (RoHS and REACH compliant). Natural translucent, white, and red silicone rubber sheet is compliant with FDA 21 CFR 177-2600 for use in food contact applications.

Individual customer specifications

SS expanded cellular silicone rubber has a predominantly closed cell structure with an integral smooth surface skin, leading to very low water absorption. It has high compressibility and low compression set over a wide temperature range, making it an ideal choice for gaskets and seals. It has excellent thermal insulation properties and is also a good acoustic insulation material at the temperature extremes where thermoplastic foams cannot be used. SS grades are suitable for long term continuous use from -60F (-50C) to 400F (204C) and for intermittent use from -80F (-62C) to 450F (232C).
