Corrosion resistance of torlon® ball
Torlon® is resistant to contact with aliphatic, aromatic, chlorurated, fluorinated hydrocarbons, most of the moderate-temperature acids, the automotive/aircraft lubricants. It can be attacked by saturated steam, strong bases, acids at high temperatures.
Torlon® Ball Applications
Special bearings (when there is no lubrication, high temperature and high wear resistance are required), automotive components (transmission). Employees in the aeronautics/aeronautics and electronics, marine/sport fishing industry.
