Description
Foreword
The thermoplastic semi-conductive shielding material for medium and high voltage cables is made of polyethylene, EVA resin and conductive carbon black as the main raw materials, adding an appropriate amount of lubricants, antioxidants and other processing aids. After mixing, extrusion and granulation made.
