Product description
The 3:1, 4:1 double-walled pipe is composed of double-layer halogen-free flame-retardant polyolefin and hot melt adhesive. The outer polyolefin is made of insulating, halogen-free and flame-retardant material. The inner layer of hot melt adhesive can buffer mechanical strain and seal strong. The main functions are sealing, waterproof, anti-corrosion, anti-leakage, multi-strand wiring harness and insulation. It is mainly used in various wiring harnesses, marine wires and metal pipes that need to be sealed, insulated, bundled and fixed.
Features
●The outer layer is flame-retardant, anti-ultraviolet, and wear-resistant
●Shrink ratio 3:1
●Environmental protection standard RoHS REACH
●Color: black, orange, red, yellow, transparent, other colors can be customized
