A formable curable elastomer composition comprising a dispersion of a cured organic elastomer, such as EPDM, butyl rubber and hydrogenated nitrile butyl rubber, is provided in an uncured silicone elastomer. The organic elastomer is cured by a phenol-formaldehyde resin. These compositions can generally be used in applications where silicone rubber is used, and in particular where the cured rubber is liable to be exposed to temperatures of 150-200° C. Examples of such uses include tyre bladders used in the moulding of tyres, spark plug boots for internal combustion engines, wire and cable coatings designed to be used at high temperatures and ceramifiable wire and cable coatings used in safety critical applications such as emergency lighting systems. |
