Abstract:
A liquid form addition curing type silicone rubber composition for roll forming purposes consisting essentially of:(a) 100 parts by weight of an organopolysiloxane with at least two alkenyl groups bonded to non-terminal silicon atoms within a molecular chain of each molecule, (b) 1 to 300 parts by weight of an inorganic filler, (c) an effective quantity of a platinum based catalyst, and (d) an organohydrogenpolysiloxane represented by a general formula (2), wherein, R3 represents either one of an unsubstituted and a halogen-substituted monovalent hydrocarbon group with no aliphatic unsaturated double bonds, each R4 represents, independently, any one of an unsubstituted and a halogen-substituted monovalent hydrocarbon group with no aliphatic unsaturated double bonds, and a hydrogen atom, and x represents an integer of 2 or greater, with at least two silicon atom-bonded hydrogen atoms within a single molecule, in sufficient quantity to produce a molar ratio of silicon atom-bonded hydrogen atoms within said constituent (d) relative to said alkenyl groups bonded to silicon atoms within said constituent (a) of 0.1 to 5.
