High Toughness 2X Heat Shrink Tube, No‑Adhesive Polyolefin Heat Shrink Sleeve, Multiple Sizes & Colors for Electrical Wiring, Copper Bar & Bus Bar Insulation

Product Description

This is 2:1 fast heat‑shrink tubing with national standard thickness, high toughness, wear‑resistant and anti‑aging, safe insulation performance up to 1000V rated voltage.

It is non‑adhesive polyolefin heat shrink tube, featuring fast 2‑times shrinkage rate. For example, Φ5mm shrinks to 2.5mm maximum, Φ10mm shrinks to 5mm maximum.

Multiple inner diameters are available: 1mm‑80mm, colors include black, red, green, yellow, blue. Length options: 2m, 10m, full roll. Sizes above 8mm are flat‑shaped.

Important Note: The model number represents the inner diameter before shrinkage, not the flattened width. Actual inner diameter is larger than marked specification (e.g., Φ1mm actual inner diameter is 1.5mm).

Widely used for wire insulation, cable repair, busbar, copper bar protection, electrical wiring harness insulation and DIY electronic projects.
