There are also guys who joked: heat shrink tube is roasted with fire, cold shrink tube shouldn't use liquid nitrogen to freeze to cool down,right?

Actually, there is no need to cool down!

The cold shrink tube is also a kind of flexible tube. It is expanded to a spiral supporting core after been enlarged. The cold shrink tube is covered on the cable joint or end.When the spiral support is pulled out, the cold shrink tube will shrink quickly like a spring and tightly adhere to the surface of the cable.

The cold shrinkable tube is made of elastic materials, such as ethylene propylene rubber (EPDM) or silicone rubber. This material also has good elasticity at room temperature, so it can rely on the molecules of the material without heating. The resilience between the space shrinks and exerts pressure on the surface of the cable, thereby sealing and protecting the cable.

Cold shrink tube can provide long-term protection for the product and performs well in indoor and outdoor environments (including harsh environment).
