PURPOSE:To obtain the subject silicone rubber composition of good weathering resistance by using an organopolysiloxane green rubber, wet-process silica, kieselguhr, powder of laterally cleaving mineral and organic peroxide. CONSTITUTION:The subject composition free from chattering and squeaking comprises (A) 100 pts.wt. of organopolysiloxane green rubber, (B) 10 to 50 pts.wt. of wet-process silica, (C) 10 to 50 pts.wt. of kieselguhr preferably of 5 to 40mum average particle size, (D) 0 to 50 pts.wt. of a laterally cleaving mineral, preferably a mica powder, (E) 0 to 10 pts.wt. of fluororesin powder such as polytetrafluoroethylene resin powder and (F) an organic peroxide such as benzoyl peroxide. |
