Semi-Rigid Single Wall Heat Shrink Tubing (Item SR230, Black, 3:1 Shrink Ratio) Description

The semi-rigid single wall heat shrink tubing is made by extruding the semi-rigid polyolefin and after radiation disposal. While ensuring insulation, the semi-rigid single wall heat shrink tubing has excellent flame retardant performance, water resistance, and mechanical protection than normal soft heat shrink tubing.

The wall thickness of the heat shrink tubing reach 3.9mm, which makes tubing suitable for outdoor cable, automotive wires and marine cables protection.
