Aflas
Aflas® Fluoroelastomer is an alternating copolymer of tetrafluoroethylene and propylene. This combination gives Aflas® Fluoroelastomer unique properties over conventional FKM-type fluoroelastomers such as high resistance to bases and excellent electrical properties. Aflas® Fluoroelastomer also displays outstanding resistance to heat, many solvents, ozone, and steam. Terpolymers of tetrafluoroethylene, propylene, and vinylidene fluoride are also available.
Benefits of Aflas® Fluoroelastomer:
Heat Resistance: Mechanical properties of Aflas® do not deteriorate even when used for prolonged exposure to 200°C. It can be used continuously for 2 to 3 months at 230°C and for 10-30 days at 260°C.
Oil Resistance: It is resistant to lubricating and hydraulic oils at high temperatures especially today's high-performance engine oils formulated with amine additives.
Steam Resistance: It is unaffected by extended exposure to 200°C steam.
Electrical Properties: It has excellent volume resistivity (greater than 1016 ohm-cm) unmatched by other fluoroelastomers.
Radiation Resistance: It is stable up to 200 MRad of gamma ray radiation.
Solvent Resistance: It offers high resistance to polar solvents such as alcohols and amines.
Acid/Alkali Resistance: Parts fabricated from Aflas® compounds perform well upon exposure to many acids and alkalis. Base resistance of Aflas® is substantially better than that of FKM fluoroelastomers. Available data and MSDS in pdf format[118 KB].
