The thin-walled heat shrink tubing with a shrink ratio of 3:1 is made of cross-linked polyolefin, is flame-retardant, and has high flexibility. The operating temperature ranges from -55 °C to +125 °C. The minimum shrink temperature is +70 °C, while the minimum temperature for complete shrinkage is +100 °C.

The RED heat shrink tubing is delivered in a practical dispenser box. This box has the advantage of allowing precise measurement of the tubing thanks to the integrated centimeter scale on the packaging. Additionally, the packaging enables clean storage of the product.
