Abstract
This invention provides heat curable compositions comprising a high viscosity, peroxide curable polydiorganosiloxane, a relatively low viscosity liquid diorganoalkenylsiloxy endblocked polydiorganosiloxane, a reinforcing filler and an effective amount of a vinyl specific organic peroxide. The tensile and recovery properties of the cured elastomer are optimized when the concentration of diorganoalkenylsiloxy groups on the liquid polydiorganosiloxane relative to the concentration of repeating units in the peroxide curable polydiorganosiloxane is within specified limits.
