Duratron™ D7040G 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™ D7040G PI maintain its performance abilities with or without lubrication, but with 40% 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.
