Abstract
A SiH-olefin platinum catalyzed composition with excellent resiliency, compression set and which can be hot air vulcanized having therein a vinyl-containing polysiloxane polymer, a hydrogen-containing polyorganio siloxane, a zero valent platinum phosphorus complex and as the novel ingredient a fine calcined silica powder with a refractive index greater than 1.446 and an ignition loss not exceeding 3% which is obtained by firing a precipitated silica.
