MAIN RAW MATERIAL PROPERTY
FFKM perfluoroelastomer compounds are has excellent high temperature resistance and chemical resistance as PTFE, but also retains the relevant properties of rubber elastomer. It can be used continuously at 260 ° C to 300 ° C and at a high temperature of 325 ° C in a short time. Such excellent performance makes it widely used in military industry, aerospace, semiconductor, medicine, electronics, chemical industry and other fields.
FKM compounds are widely used in chemical, automotive, aerospace and industrial applications, Fluoroelastomer (Viton®, FKM) offers a wide range of resistance to chemicals, oil and heat, with situational service life above 200°C, with Excellent mechanical properties. Good extrusion resistance. Chemical and heat resistant.
NBR offers relative low cost, good mechanical properties, and resistance to many common oils, fuels and lubricants. NBR has poor resistance to weathering, sunlight and ozone so it is best used in enclosed environments where parts are not exposed to the elements.
HNBR Hydrogenated versions of NBR (HNBR) have enhanced mechanical properties as well as greater thermal and chemical stability. Specific physical properties and chemical resistances vary by compound formulation.
Silicone are excellent seal materials for extreme temperature in static applications. Outstanding flex and fatigue life, very good for ozone and UV radiation, insulating properties, and physiologically neutral. silicones can be synthesized with a wide variety of properties and compositions.
PTFE with Best chemical compatibility, low friction, meets FDA, USDA and 3-A dairy requirements, excellent moisture resistant and good cryogenic capabilities down to -350° F. Could be applied in Seals, bushings, back-ups, guides, pads, plugs, rollers, spacers, o-rings, wear rings, washers.
