High-temperature resistant sealing ring (sliding friction)
Thread Content
Dear teachers, may I ask if seals that can be used in conditions of sliding friction at temperatures above 400 degrees are available? Are there any recommended materials? For leaks at level IV or above, thank you first
I can’t think of any above 400 degrees for now
That’s the problem. Over 400 degrees. If graphite is used. There are cases of graphite failure.
If the operating temperature is above 400 degrees over a long period of time, it is likely to be quite difficult. The PI currently under development can reach over 350 degrees on a long-term basis, and up to 450 degrees in the short term.
So what is the leakage level that this PI sealing ring can achieve?

So when will this product be available on the market? Could you let me know through your company’s website? Thank you, I hope we can have further cooperation.
This material is already available, but it’s not widely available on the market. If you need it, you can leave me your email address; I’ll need details about your usage conditions, and a private message will work as well.
In the case of hard-sealed sliding. Lifetime and leakage level are the challenges
