EPDM cold shrink environmental seal
EPDM cold shrink environmental seal is also cold EPDM cold shrink tubing, easy and fast install, alternative to heat shrink tubing, no need heat guns and other tools, resistant to moisture, acids, alkalis and UV light, this pre-stretched tubing is suitable as primary insulation on a range of 1000v cables, copper and conductors.
What’s the difference between cold shrinking and heat shrink tubing?
Comparing cold shrink tube with heat shrinkable tube, the cold shrink tube no need to be heated. Physical method pre expands the EPDM or silicone rubber bushing into the support bar, and draws the support bar, the cold shrink tube will shrink back.
The cold shrink tubing contract by pulling out the supporting core, but the heat shrinkable tube shrink by heating. The difference between the two is as follows:
1. The material is different, the cold shrink tube is generally made of silicone rubber and three ethylene propylene rubber. The heat shrinkable tube is a polyolefin material.
2. The use of the environment is different. The cable joint cold shrink tubing suitable for no heat/fire site, but heat shrink tube need heating/fire to shrink.
3. Cold shrink tube has the advantages of simple operation, less demand for workers proficient, but when installing the heat shrinkable tube, it required to pay attention to the construction techniques.
4. The inner diameter of the cold shrink tubing is generally above 14mm, and the size/ID scope of the heat shrinkable tube is basically unrestricted, we can produce heat shrink tubing ID from 0.6mm to 250mm.
