1. In terms of price: EPDM rubber material is cheaper than silicone rubber material.
2. In terms of processing: Silicone rubber is better than EPDM.
3. In terms of temperature resistance: Silicone rubber has better temperature resistance, EPDM rubber has a temperature resistance of 150℃, and silicon rubber has a temperature resistance of 200℃.
4. Weather resistance: Ethylene-propylene rubber is better weather-resistant, and the rubber itself is environmentally friendly, but it is less likely to breed bacteria in a humid environment.
5. Shrinkage ratio expansion ratio: The shrinkage ratio of silicone rubber cold shrink tubing is now higher than that of EPDM cold shrink tubing.
6. The difference in burning: When burning, the silicone rubber will emit a bright fire, almost no smoke, no smell, and white residue after burning. EPDM, there is no such phenomenon.
7. In terms of tearing and puncture resistance: EPDM is better.
8. Other aspects: Ethylene-propylene rubber has good ozone and high strength; high hardness and poor low temperature brittleness; silica gel has good elasticity and good low temperature performance; ordinary ozone, low strength!
