Product Description

Application: it is mainly used in sealing, insulation, binding and fixing of various wire harnesses, marine wires and cables and metal pipes where sealing, waterproof, moisture-proof and anti-corrosion are required


The double wall pipe is composed of halogen-free flame-retardant polyolefin and hot-melt adhesive. The outer layer is halogen-free and flame-retardant polyolefin insulation material. The inner layer of hot-melt adhesive can buffer mechanical strain and has strong sealing performance. The main functions are sealing, waterproof, anti-corrosion, air leakage and insulation protection. It is mainly used in the fields of sealing, insulation, binding and fixing of various wire harnesses, marine wires and cables and metal pipes where sealing, waterproof, moisture-proof and anti-corrosion are required.
