ABSTRACT:
The silicone rubber composition of the present invention comprises (A) an organopolysiloxane obtained by mixing and heating an organopolysiloxane having a silanol group at both ends of the molecular chain and a silane or a siloxane having two hydrolyzable groups in the molecule, (B) a finely divided silica, and (C) a curing agent. The composition, wherein the content of low-molecule siloxanes is remarkably constrained, is quite useful in the application wherein low-molecular siloxanes are obnoxious, for example, in the application of electrical contacts and parts used adjacent thereto, roll materials of copying machines, gaskets for construction, etc.
