- Features
- Excellent hot melt adhesive and high shrink ratio provide excellent sealing properties
Military standard double-wall heat shrink tubing is made of high-quality polyolefin and hot melt adhesive co-extrusion. The outer polyolefin is a highly flame-retardant insulating material with good sealing and insulation properties, superior electrical and physical properties, and high flame retardancy. and other characteristics. It can complete moisture-proof sealing, insulation and mechanical protection in one go. Produced in accordance with military industry standards, the main functions are sealing, waterproof, moisture-proof, anti-corrosion, anti-leakage, multi-strand wire harness and insulation. Hot melt adhesive has good connection properties with plastics, rubber, and metals. It is mainly used for insulation, bundling and fixation of various types of wire harnesses, marine wires and cables and metal pipes that need to be sealed, waterproof, moisture-proof, and anti-corrosion. It is suitable for military standard level fields.
