Heavy Wall Heat Shrink Tubing

Heavy Wall Heat Shrink Tubing, SBRSW Model: SBRSW Flame retardant, adhesive-lined cross-linked polyolefin heat shrinkable tubing

SBRSW heavy wall heat shrink tubing is flame-retardant adhesive-lined heat shrink tubing made from cross-linked polyolefin. This heat shrink tubing is ideal for insulation and protection of electrical splices and terminations where maximum flame retardancy and exceptional environmental sealing capabilities are required.

Features 3:1 shrink ratio Flame retardant SBRSW heavy wall heat shrink tubing will not split or rupture during installation, when overheated Thermoplastic adhesive liner for complete environmental protection and insulation Continuous operating temperature: -45℃～125℃ Fully shrink temperature: 125℃ Dimensions
