As a leading and professional manufacturer of cold shrink tube, both EPDM cold shrink tube and Silicone rubber cold shrink tube are our typical and hot sale products. Do you know what is the main difference between EPDM and Silicone rubber material?
We will list the difference between EPDM rubber and silicone rubber here, and would like to talk from different aspects.





1. Processing: silicone rubber is better than EPDM rubber.
2. Temperature resistance: silicone rubber has better temperature resistance, EPDM rubber has a temperature resistance of 150 °C, and silicone rubber has a temperature resistance of 200 °C.
3. Weather resistance: EPDM rubber has better weather resistance and the rubber itself is environmentally friendly, but in a humid environment, EPDM rubber is less likely to breed bacteria.
4. In terms of expansion ratio of shrinkage ratio: Now the shrinkage ratio of silicone rubber cold shrinkable tube is higher than that of EPDM rubber cold shrinkable tube. It is 5:1 shrink ratio.
5. Differences in combustion: When burning, silicone rubber will emit a bright fire, almost no smoke, no odor and white residue will be left after burning. EPDM rubber, there is no such phenomenon.
6. In terms of tear and puncture resistance: EPDM rubber is better.
7. Other aspects: EPDM rubber has good ozone resistance and high strength, high hardness, but poor low temperature brittleness; while silica gel has good elasticity and low temperature resistance; but the ozone resistance is general and the strength is low.
