Both EPDM and silicone rubber cold shrink tube are our main cold shrink products. Due to the different raw material, even though both them belong to cold shrink technology, there are still some difference.
As we all know, EPDM (Ethylene Propylene Diene Terpolymer) cold shrink tube, can be used in harsh environment also suitable for power cable under 1KV, can be used in indoor and outdoor, overhead, in water or buried occasions, etc.
Compared to silicone cold shrink tube, EPDM tube is more resistant to abrasion, puncture and acid and alkali. Because of its unique properties, EPDM tube is most used in industrial applications like power cable, coaxial cable, etc. 

Silicone cold shrink tube is made of special silicone rubber material, which has the advantages of large shrinkage ratio, excellent physical and mechanical properties and weatherproofing resistance, etc. Also, its continuous working temperature can be -60℃~200℃. Widely used for insulation protection of communication connector, cable connection and antenna, feeder in telecom base station.
