ABSTRACT:
Mixing under low shear vinyl-containing polyorganosiloxane, a silicon-bonded hydrogen polysiloxane and a platinum catalyst, and continue mixing produces a crumb which has an extrusion rate of at least 50 grams per minute through an orifice of 0.5 inch diameter under a pressure of 345 kilopascals and compression points of less than 1035 kilopascals. The crumb is useful in hydraulic applications.
