Model No.: Duratron® D7015G 15% Graphite-filled PI
Brand: Duratron
| Selling Units | : | Kilogram |
| Package Type | : | Export package |
Duratron® D7015G PI Polyimide is a bearing grade PI that exhibits superior temperature and wear resistance qualities, while offering a low coefficient of friction. Not only does hot compression molded Duratron® D7015G PI maintain its performance abilities with or without lubrication, but with 15% graphite added to provide long wear and low friction, it is a great choice for bearing, bushing, and seal applications where higher loads or speeds are a significant factor.
