Corrosion resistance of PEEK ball
PEEK balls are resistant to contact with most solvents (organic components, salts, oils), hot water and high temperature steam. They are attacked by strong acids (concentrated nitric acid, sulphuric acids), halogens and certain aromatic hydrocarbons.
Applications of PEEK ball
Special bearings, pumps and valves, components of the chemical, electronic and mechanical industry when high mechanical and corrosion resistance characteristics are required.
