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.
Benefits of Aflas® Fluoroelastomer:
- Heat Resistance: Mechanical properties of Aflas® do not deteriorate even when used for prolonged exposure to 200°C. Aflas® can be used continuously for 2 to 3 months at 230°C and for 10-30 days at 260°C.
- Oil Resistance: Aflas® is resistant to lubricating and hydraulic oils at high temperatures especially today\'s high-performance engine oils formulated with amine additives.
- Steam Resistance: Aflas® is unaffected by extended exposure to 200°C steam.
- Electrical Properties: Aflas® has excellent volume resistivity (greater than 1016 ohm-cm) unmatched by other fluoroelastomers.
- Radiation Resistance: Aflas® is stable up to 200 MRad of gamma ray radiation.
- Solvent Resistance: Aflas® 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.
