High Sealing Adhesive-Lined Polyolefin Heat Shrink Tubing
Basic Info
Basic Info.
3:1 shrink ratio to cover varying splice configurations and substrate profiles.
Flame-retardant and strong sealing, the tubing provides strain relief and abrasion protection of wire splices, terminals, and other components.
Thick adhesive liner forms an effective barrier against fluids and moisture penetration.
Minimum shrink temperature: 70°C .
Continuous operating temperature: -45°C to 125°C .
Fully shrink temperature:125℃.
Wear resistance and UV resistance.
Application:
Sealing waterproof, anti-corrosion, leakproof, multi-strand wire harness and insulation
Wire harness
Marine wire and cable
Metal pipe need to seal waterproof, moisture-proof, anti-corrosion sealing insulation, binding fixed

Advantages:
It consists of a double layer of cross-linked polyolefin and polyamide PA. It has the characteristics of good flame retardancy and strong sealing, and is mainly used in various fields such as sealing, insulation, bundling, and fixation of wire harnesses and metal pipes that require sealing, waterproof, moisture-proof, and anti-corrosion.
