What’s the difference between Cold shrinking and heat shrink tubing?
Cold Shrink and Heat Shrink tubing may appear similar from the outside, but their key characteristics are very different,both types of tubing have different installation techniques, applications and physical properties.
Heat Shrink and Cold Shrink tubing can be used for a variety of cabling applications including: terminating, splicing and providing environmental seals on LV and MV cables. More than price, ease of use and environmental conditions should be taken into consideration when choosing the most suitable product.
The most obvious differences between the two products are how each of them is applied. Cold Shrink comes stretched over a removable plastic core, allowing the tube to be slid over the application, the core removed and the tubing will contract to create a watertight-seal around the cable or connection due to the ‘active memory’ contained within the EPDM rubber or silicone material. Heat Shrink, also comes pre-stretched but as a sleeve rather than over a removable core. The sleeve requires a heat source for installation, usually from a gas torch, to heat the polyolefin tubing so that it shrinks to its original size, creating a seal over the cable or joint.
