Abstract
A silicone rubber base compound for electrical wire coating such that when it is extruded using an extruding machine having a variable screw with an L/D=10 and a die with a diameter of 1 mm attached thereto at a barrel and head temperature of 70.degree. C., the per-minute extruder output rate at a screw rotation speed of 100 rpm is not less than 1.2 times the extruder output rate at a screw rotation speed of 50 rpm, a silicone rubber composition for electrical wire coating obtained by compounding diacyl organic peroxide consisting of carbon atoms, hydrogen atoms, and oxygen atoms with the silicone rubber base compound for electrical wire coating, and a process for the production of silicone rubber coated electrical wire using the silicone rubber composition for electrical wire coating.
