Abstract:
1. A curable silicone rubber composition, comprising: (A) an organopolysiloxane containing two or more aliphatic unsaturated groups bonded to silicon atoms within each molecule, having a viscosity at 25° C. within a range from 500 to 500,000 mm (B) an organopolysiloxane resin with a three dimensional network structure, consisting essentially of SiO (C) an organohydrogenpolysiloxane, and (D) a platinum group metal-based catalyst, wherein said component (B) exists in a quantity that represents from 20 to 80% by mass of a combination of said component (A) and said component (B), and within said component (B), a quantity of low molecular weight substances, for which a weight average molecular weight measured by gel permeation chromatography and calculated against polystyrene standards is not greater than 500, is not greater than 5%.
