Today I will share some application cases and technical performance of the EPDM cold shrink tube with you here. As we know, EPDM cold shrink tube is more wear resistant than the silicone rubber type. It’s widely used for the cable jointing insulation and protection of the electric power industry. 



Here are 7 main features of the EPDM cold shrink tube:

1.EPDM is the main material which is with excellent weather resistance and UV resistance


2.It can be used in outdoor, underground and coastal environment, with excellent acid mist corrosion resistance, acid and alkali resistance, puncture resistance and moisture resistance


3. No heating or open flame, easy to install.Can be widely used in places where open flames are strictly prohibited, such as coal mines and other places where low-voltage cable connections are sealed


4. Easy installation, no special installation tools are required.It’s suitable for various cable sizes


5. Breathe with the cable to achieve active sealing


6. The seal is tight, the radial pressure is large and the resilience performance is good


7. Excellent resistance to mechanical damage



Application range: 

The excellent weather resistance and bacteria resistance of EPDM rubber which ensure that the cold shrink tube can be widely used in outdoor, underground and coastal environment.It is suitable for low-voltage power cables of various specifications and wireless base station coaxial cable joints.It has good insulation, sealing, Waterproof, anti-salt spray corrosion, etc.


This is the technical performance of our EPDM cold shrink tube for reference:
