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, ??5mm shrinks to 2.5mm maximum, ??10mm 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.
