Product Overview

FFKM perfluoroelastomer rubber is a special top-grade perfluorinated material with the strongest comprehensive performance among all rubber elastic sealing materials. All hydrogen atoms in the molecular structure are completely replaced by fluorine atoms, combining the ultimate chemical stability of PTFE and the excellent elastic sealing performance of rubber. Different from conventional sealing materials such as ordinary FKM, EPDM and acrylate rubber, FFKM is not afraid of strong acid and alkali corrosion, organic solvent dissolution, high-temperature steam aging, plasma etching and nuclear radiation erosion. It maintains stable long-term sealing without hardening, swelling, cracking or leakage under extreme harsh working conditions where other rubbers fail quickly. All FFKM perfluoroelastomer seals are precisely processed with imported high-quality original raw materials, featuring small permanent compression deformation and excellent rebound sealing performance. Perfect for precision equipment sealing points with ultra-high requirements, replacing imported brands for a long time and greatly reducing equipment operation and maintenance costs.

Raw Material & Grade Selection

The production technology of perfluoroelastomer rubber has high technical barriers, and only a few global manufacturers can produce raw materials. We strictly select original imported FFKM raw materials from the United States, Japan Daikin and Europe Solvay, with high material purity and stable performance. According to different temperature resistance grades, corrosion resistance formulas and working condition strength, we stock six mainstream standard grades: FF460, FF325, FF380, FF580, FF880, FF980, covering low-temperature conventional, medium-temperature general, high-temperature high-strength, ultra-high cleanliness and special radiation-resistant requirements. Custom high-purity metal-ion-free grades are available to meet high-precision production environments such as semiconductors, laser electroplating and biomedicine. Professional engineers provide one-to-one accurate selection according to working conditions.
