Abstract
A silicone rubber is produced by curing a silicone rubber composition which includes (A) a curable organopolysiloxane composition and (B) at least one hollow organic resin filler whereby the filler forms cells in an open-cell state. The open-cell state gives the silicone rubber good cushioning property and a low compression set.
Claims10
A method of producing a silicone rubber, said method comprising the step of curing a silicone rubber composition comprising (A) a curable organopolysiloxane composition and (B) at least two hollow organic resin fillers of different softening points, at a temperature at which the lower softening point hollow filler collapses and the higher softening point hollow filler substantially maintains its shape.
A silicone rubber produced by curing a silicone rubber composition comprising
- (A) a curable organopolysiloxane composition, and
- (B) at least two different hollow organic resin fillers whose difference of softening point between the lower softening point hollow filler and the higher softening point hollow filler is 5 to 100° C.,
- in which silicone rubber the filler forms cells in an open-cell state.
