General Information
The environmentally friendly double-walled(dual wall) pipe is composed of a double layer of soft flame-retardant polyolefin and hot-melt adhesive. The outer layer is polyolefin insulated and flame-retardant material, and the inner layer of hot-melt adhesive can buffer mechanical strain and have a strong seal.
The main function of the product is sealing, waterproof, anti-corrosion, air leakage and insulation protection. The high-magnification shrinkage characteristic can meet the protection of more variable diameter components.
Mainly used in various wiring harnesses, marine wires and cables, and metal pipes that need to be sealed, insulated, bundled and fixed where waterproof, moisture-proof and corrosion-resistant applications are required.
