THINKRE® Series FFKM Perfluoroether Rubber

The KERUN Thinkre® series of perfluoroether elastomers can be used to manufacture gaskets, O-rings, V‑shaped seals, oil seals, diaphragms, hoses, cable jackets, thermal insulation fabrics, valve discs, expansion joints, rubber rollers, coatings, and other products designed for applications requiring resistance to high temperatures, chemical corrosion, radiation, and atmospheric aging. This series exhibits excellent high‑temperature stability and chemical‑solvent resistance, while also offering low permeability, superior plasma‑etching resistance, and outstanding reliability with a long service life.
