SILICONE RUBBER COMPOSITION FOR EXTRUSION MOLDING AND METHOD FOR PRODUCING SILICONE RUBBER EXTRUSION MOLDED ARTICLE

摘要

PURPOSE: To provide a silicone rubber composition for extrusion molding which has a high curing rate and which can be a silicone rubber extrusion molded article with little blooming and surface tack after curing, and to provide a method for producing the article. CONSTITUTION: This composition comprises (A) a silicone rubber base compound of 100 pts.wt., which is composed of (a-1) a diorganopolysiloxane raw rubber, (a-2) a reinforcing silica, and (a-3) an organosiloxane oligomer of which the both terminal silanol groups have been hindered or a hexaorganodisilazane, (B) an organic peroxide of 0.1-10 pts.wt. which is represented by the formula: R-COOOCOO-R1-OOCOOOC-R and (C) an alkyl organic peroxide of 0.05-10 pts.wt.
