| 100% New Raw Rubber | VS | Recycled Rubber | |
|---|---|---|---|
| Select material | 100% raw rubber material, make same to original car seal strip | From all kinds of recycled waste products, the processing process can also be mixed with a lot of impurities | |
| Physical difference | Soft, flexibility, light density, good stretch | Generally more hard, poor elasticity, more weight than same size seal strip | |
| Smell difference | The smell is relatively small and usually disappears after a few days | Smell is bigger, in addition to rubber flavor will be mixed with other odor, odor is difficult to volatilize | |
| Service life | Good wear resistance, high stability, long service life | The service life is short, the aging is quick and easy to become hard and even appear to break and break |
1)Based on operating conditions (such as temperature), what material do you recommend?
EPDM : Working temperature range 40℃ ~ +120℃. Excellent resistance to weather, ozone and water. Widely used for doors & windows, general mechanical cabinet seals.
Silicone rubber (VMQ): Working temperature range 60℃ ~ +200℃. Outstanding high low temperature resistance, suitable for high temperature equipment. Poor oil resistance, not fit for oily medium environment.
NBR/nitrile rubber: Working temperature range 30℃ ~ +110℃. Good oil resistant property, ideal for machinery contacting oil medium but not good for long term outdoor aging.
CR/neoprene rubber: Working temperature range 35℃ ~ +100℃. Balanced performance of weather resistance and oil resistance.
Above data is for reference only. The final material and cross section structure also depend on contact media. Offer your exact working conditions, we can confirm the best solution for you.
