Cold shrink sleeving made from silicone rubber or EPDM material, no need to heat, it can shrink back by itself once the supporting bar is pull out from tubes, the purpose of supporting bar is stop tube shrink before installation.
How can cold shrink sleeving shrink back by itself?
Cold Shrink tubing has an “active memory” seal characteristic, meaning the tubing is always trying to return to its original size and able to maintain its sealing capability around cables as they expand and contract under large load-swings or temperature fluctuations.
Silicone rubber Cold Shrink tubing has the greater UV-resistance of all the types of cold or heat-applied tubing and is therefore used in outdoor, exposed environments, for example: trackside terminations to rail power lines. EPDM rubber is also used in Cold Shrink tubings and is much more abrasion resistant than other cold or heat-applied products, being ideally suited for direct burial applications such as cable-to-cable jointing.
