DUWAI HS3X 3:1 Heat-Shrinkable Tube Environmentally Friendly Double-Wall Pipe with Hot Melt Adhesive Lining for Enhanced Reliability
HS3X&HS4X (3:1, 4:1) halogen-free environment-friendly double-wall pipe is composed of soft polyolefin and hotmelt adhesive double layer, the outer polyolefin insulation material, the inner layer of hot melt adhesive can buffermechanical strain and strong sealing. The main function of the product is sealed waterproof, anti-corrosion, antieakage and insulation protection, high rate shrinkage characteristics can meet the protection of more variablediameter components. Mainly used in all kinds of wire harnesses, Marine wires and cables and metal pipes need to besealed waterproof, moisture-proof and corrosion-proof sealing insulation, binding and fixing fields.
