Flame Retardant Dual Wall Polyolefin Heat Shrink Tubing
Basic Info
Basic Info.
4:1 shrink ratio to cover varying splice configurations and substrate profiles
Jacket and adhesive are exceptionally flame retardant
Economical way to environmentally seal and protect automotive fuse-links, splice and terminals
Highly resistance to common automotive fluids and solvents
Semi-rigid and mechanically tough outer jacket provides added strain relief and excellent abrasion protection
Thick adhesive liner forms an effective barrier against fluids and moisture penetration
Continuous operating temperature:-45℃-125℃
Fully shrink Temperature:≥125℃
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
