METHOD FOR MANUFACTURING CROSSLINKED POLYOLEFIN ELECTRIC WIRE AND CABLE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a recyclable crosslinked polyolefin electric wire and cable that can secure excellent fluidity by changing the structure of the crosslinked polyolefin. SOLUTION: A silane crosslinking polymer is formed by grafting an unsaturated silane compound onto a copolymer of ethylene having 25 or more content of such comonomer as a vinyl acetate, an ethyl acrylate, a butyrate or the like. A mixture gained by mixing the silane crosslinking polymer and a polyethylene extrudes to cover a conductor. Then, the mixture is crosslinked in steam.
