SILICONE PRODUCT DATA
What is Silicone Rubber Sponge?
Silicone rubbers are substances whose chemical skeleton is made up of extremely stable silicon-oxygen linkages. They are chemically related to quartz and glass and many of their excellent properties are similar to those of the latter material. During vulcanisation they are cross linked, with the appropriate use of fillers, catalyst and blowing agent etc., to form a three dimensional, flexible, sponge like substance. After the vulcanisation process is complete the general appearance of silicone sponge is a fine non-interconnecting cell structure encapsulated by a soft smooth outer surface skin. Silicone sponge components offer excellent thermal stability in the most exacting of applications and has the ability to withstand extreme variations in temperature from -50 C up to +250 C.
