ELECTRICALLY CONDUCTIVE POLYPROPYLENE FILM

摘要

PURPOSE:A film, obtained by blending specific polypropylene with carbon black and having god electric conductivity and heat resistance and improved thickness accuracy without crease. CONSTITUTION:A film obtained by blending (A) 100pts.wt. polypropylene containing at least 3wt% propylene-alpha-olefin random copolymer with (B) 5-50pts. wt. carbon back. A propylene-alpha-olefin random copolymer with 0.1-6wt% is used as the propylene-alpha-olefin random copolymer and polypropylene of 100wt% above-mentioned copolymer is preferred.
