Both EPDM rubber and silicone rubber can be used for cold shrink tubing and heat shrink tubing. What is the difference between these two materials?
1. In terms of price: EPDM rubber materials are cheaper than silicone rubber materials.
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°C, and silicon rubber has a temperature resistance of 200°C.
4. Weather resistance: Ethylene-propylene rubber is better weather-resistant, and the rubber itself is environmentally friendly, but in a humid environment, ethylene-propylene rubber is less likely to breed bacteria.
5. Shrinkage ratio expansion ratio: now the shrinkage ratio of silicone rubber cold shrink tubing is higher than that of EPDM cold shrink tubing.
6. The difference in combustion: 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!
