ABSTRACT:
A novel composition is disclosed which contains a silicone polymer, a non-silicone polymer other than polytetrafluoroethylene and a chemically treated filler. The non-silicone polymer may be an elastomer or a thermoplastic such as a polyolefin, a copolymer containing an olefin, a halogen-containing polymer or copolymer or a copolymer of fluorine-containing polymers other than polytetrafluoroethylene. The filler is an inorganic silicon-containing compound having a surface area of at least 40 square meters per gram which has been treated with a substituted silane. The treated filler is first blended with the non-silicone polymer and this compound is then mixed with the silicone polymer.
