Hello to everybody!
I am trying to find a material the name I have is Polybon MT0454, it is a carbon fiber and graphite filled polyimide bearing material, the Rolls Royce Part Number is MSRR 9384.
Has someboby hear from this product? it is very urgent to find the equivalent name, where to buy.

I have been searching this product for a while. I know this used to be a Dupont product, but being asked at the JEC, Dupont does not seem to know anything about this. I can send commercial datasheets if needed.
