PCTFE

This is a plastic bearing that can be used for hydrofluoric acid cleaning of semiconductors and LCDs. We are the only company in Japan that manufactures ball bearings from PCTFE (Polychlorotrifluoroethylene). Plastic Bearings for Cleaning with Hydrofluoric Acid Our bearings have a specification of PCTFE (Poly Chloro Tri Fluoro Ethylene) for the main body and SiC (Silicon Carbide) for the balls. Hydrofluoric acid, used in the cleaning of semiconductors and LCDs, corrodes many metals, plastics, and ceramics. We manufacture PCTFE bearings that are resistant to hydrofluoric acid. PCTFE: Poly Chloro Tri Fluoro Ethylene (Polychlorotrifluoroethylene) is a hard plastic that has proven to be particularly resistant to hydrofluoric acid. Depending on[…..]
