XLPE-UV cable insulation material

Product Introduction

The UV-crosslinked polyethylene insulation material series products are mainly made of polyethylene as raw material, with photoinitiators, crosslinkers, antioxidants and processing aids added, and are made by twin-screw extrusion and granulation. The products have excellent mechanical properties and strong resistance to environmental stress cracking; they are easy to process and have a fine and smooth surface.

Application

The products reach the crosslinked state after being irradiated by LED UV crosslinking equipment in the molten state, which fully complies with the JB/T10437-2004 standard.
