Abstract
A heat shrinkable silicone tube is prepared from a silicon rubber composition comprising (A) a diorganopolysiloxane, (B) a thermoplastic resin, (C) finely divided silica, (D) an inorganic filler of titanium white, alumina, quartz powder or talc having a mean particle size of 0.5-15 .mu.m, and (E) a curing agent by extrusion molding the silicone rubber composition into a tubular shape preferably at a drawdown of 150-250%, vulcanizing the tube, and heat stretching the tube in a radial direction. The tube exhibits axial orientation during the stretching step and a shrinking step subsequent thereto and is thus tearable.
