XJ-VDE CHLORINATED POLYETHYLENE (CPE) COMPOUND FOR VDE STANDARD CABLE'S INSULATION JACKETS
I.PRODUCT FEATURES:
Various grades of CPE compound for cable & wire's insulation jackets can be designed&produced according to the European standard.This compound is mainly produced with CPE/EPDM mix, it has good processing ability,excellent insulating property and air-bomb ageing resistance,at the same time,it can reduce the cost greatly compared to its solely compound EPDM .
