What are the temperature resistance of nitrile rubber seals?

Nitrile rubber is often used to make various sealing products such as O-rings, oil seals, cups, etc. It is often used for sealing in general hydraulic and pneumatic systems. What about the temperature resistance of nitrile rubber seals?

Nitrile rubber sealing ring has better heat resistance. Its heat resistance is better than neoprene. The long-term use temperature can reach 100~120℃. The high temperature resistance is about 10℃ higher than that of neoprene. The general use temperature range: About -45℃~+130℃.

As we all know, nitrile rubber seals have good oil resistance, abrasion resistance and heat resistance, but many people do not know that some media of nitrile rubber are not suitable. For example: nitrile rubber seals are not suitable for phosphate ester series hydraulic oils and In the gear oil with pressure additives, the selection should not only look at the temperature resistance and size of the nitrile rubber seal, but also need to consider the performance requirements that need to be met.
