Abstract

A curable silicone rubber compsn. is made by (a) forming a mixt. of easily flowable particles from a viscous, adherent, cohesive silicone polymer and a filler pref. using solid CO2 and mechanical shear, (b) feeding the mixt. continuously to an intense mixing device, pref. a 2-roll rubber mixer, so that a plastic mass is formed, (c) evacuating the mass continuously from the mixer. pref. as a series of films and (d) shaping the mass, pref. by extruding and cutting up into pellets. The process allows easy and rapid mixing of the rubber with extending fillers, pigments and catalyst, without requiring a paste mixer.
