Perfluororelastomer FFKM Series is sealing product developed by JST to meet the increasingly demanding sealing needs of equipment manufacturers and users in semiconductor, petrochemical, mechanical seal, instrumentation, energy, biopharmaceutical, food and medical industries. In addition to chemical inertness and thermal stability, FFKM also has the unique elasticity and durable sealing force of synthetic rubber. FFKM has excellent chemical corrosion resistance and high temperature resistance characteristics, which makes FFKM widely used in various harsh working conditions for chemical applications.

With many years of experience, we provide a wide range of standardized materials in the industry and continuously develop new materials for customer applications.

JST´O-Ring Family

• NBR/HNBR/VITON/AFLAS/EPDM/PU/PTFE O ring
