Silex Silicone Rubber Spronge. Profile extrusions, sheeting, cord, joined rings, punched forms, and pressure-sensitive adhesive backing. This range of polydimethylsiloxane has been “free-blown” with a chemical blowing agent and crosslinked with an organic peroxide. The cellular structure is produced without the use of CFC’s thus making it less damaging to the environment. The range is suitable for continuous use at temperatures up to +200ºC. See our “HT” grades for use up to + 270ºc. They are also suitable for use at temperatures as low as -60ºC.
Silicone rubber has excellent resistance to ozone, oxidation, ultraviolet light, corona discharge, cosmic radiation, ionising radiation and weathering in general.
Closed Cell - Can be compressed to meet IP65
Cellular silicone rubber is suitable where a soft, easily deformed rubber is required, for example, for high temperature seals and gaskets. The sheets and punched parts are all available with pressure sensitive adhesive backing to ease assembly.
