Extruded Silicone Rubber Profiles is the highest performing polymer which was originally developed to insulate electric motors and generators. Silicone rubber is made from silicone metal and silicone sand. Silicone rubber is found in three forms: a room temperature vulcanization kit, in liquid form, and as a high consistency rubber. In its uncured form, the consistency of high consistency rubber silicone ranges from soft putty to cheddar cheese. Silicone rubber does not have high viscosity.
