Document Type and Number:
Japanese Patent JP6809444
Kind Code:
B2
Abstract:
To provide a liquid silicone rubber sponge composition providing a silicone rubber sponge having high strength and high durability, and an electrophotographic image forming member.SOLUTION: The liquid silicone rubber sponge composition is provided that includes: 100 pts.mass of liquid organopolysiloxane (A) having a silicone atom-bonded alkenyl group; 1-100 pts.mass of a three-dimensional net-like organopolysiloxane resin (B) in which 0.05-0.15 mol/100 g of an alkenyl group are bonded to only D units, and a ratio of T units to T and/or Q units is 0.65-1.40; silicon atom-bonded hydrogen-containing organohydrogenpolysiloxane (C) in such an amount that an amount of the silicon atom-bonded hydrogen atom number of the (C) constituent is 0.7-10/one of total silicon atom-bonded alkenyl groups in the (A) constituent and the (B) constituent; 0.5-1,000 ppm of a platinum group metal catalyst (D) with respect to a whole composition; and a foaming agent (E) in such an amount that the density of the obtained silicone sponge becomes 0.9 g/cmor smaller.SELECTED DRAWING: None
