Black PE sheath for wire and cable

Product introduction

The black PE sheath material of our factory is a new type of sheath material for production communication cable (fiber optic cable).. The product has excellent weather resistance, toughness, wear resistance and excellent resistant environmental cracking, but also has good processing performance and softness, the physical and mechanical properties and electrical properties have reached or exceeded the standard requirements. Can be used in the manufacture of all kinds of communication cable sheath, with good resistance to stone ointment performance and also can be used to control cable and signal cable support layer and aerial cable insulation and ultra high voltage power cable outer sheath.
