TECHNIQUES FOR INSULATING WIRE AND CABLE WITH SILICONE RUBBER,

Abstract

A roller feed, together with a hat, makes an effective mechanical feed for silicone rubber extruders. Such a feed reduces the labor required in the extruding operation. A single flight, decreasing pitch screw with a compression ratio of about 3 to 1 seems to give best all-around results when extruding silicone rubbers. When insulating wire with silicone rubber and vulcanizing in a hot air vulcanizer, extrusion speeds can be increased greatly by preheating the conductor to 300 to 400F. Semi-vulcanized silicone rubber tape is an excellent material for insulating large size conductors, providing advantages over currently used taped constructions utilizing fully cured tapes. (Author)
