Halogen Free Flame Retardant Dual Wall Tube, Triple-Wall Heat Shrink Tubing with Adhesive
Product Overview
DWHS – (3x) H {3 : 1) halogen-free flame retardant dual wall tube is composed of halogen-free flame retardant material and hot melt adhesive. The outer layer is halogen-free and flame retardant polyolefin insulation material, and the inner layer hot melt adhesive can buffer mechanical strain and has strong sealing performance.
The main functions are sealing, waterproof, anti-corrosion, anti-leakage and insulation protection. It is mainly used in all kinds of wire harness, marine wire and cable and metal pipe, sealing, insulation, binding and fixing in the situation of sealing, waterproof, moisture-proof and anti-corrosion.
