AFLAS^® Fluoroelastomers

AFLAS is the registered tradename for a unique fluoroelastomer based upon an alternating copolymer of tetrafluoroethylene and propylene ("TFE/P"). AFLAS, when properly formulated, can be used to fabricate o-rings, gaskets, and seals possessing several unique properties:

• excellent heat resistance with 230°C continuous service temp capability,
• chemical resistance including resistance to strong acids and caustics,
• high electrical resistivity, and
• excellent oil resistance.

Seals Eastern, Inc. was one of the earliest companies to formulate AFLAS and develop applications in the oilfield, fluid control, heavy duty diesel, steam, and other industrial uses. Seals Eastern and its founder have been acknowledged countless times for advancements in the application technology of AFLAS materials. Such recognition has come from several elastomer industry leaders, including Dyneon LLC as shown here. Contact Us to learn more.

AFLAS is categorized under the ASTM D1418 designation of FEPM. AFLAS is a copolymer of tetrafluoroethylene (TFE) and propylene (P). On account of this molecular structure, AFLAS has outstanding base resistance (e.g. caustics, alkalines, amines, nucleophiles) unlike other fluorocarbon polymers that contain vinylidene fluoride.

Do not be fooled by cheap AFLAS o-rings and seals since they often lack proper postcuring techniques, contain reground material, and blends of cheaper fluorocarbon polymers all of which cause inferior performance and leaks.
Seals Eastern guarantees its 7182^TM series AFLAS formulations are 100% virgin AFLAS polymer and post-cured using state-of-the-art cure technology. All of our o-rings meet or exceed ISO quality standard ISO3601-3 Grade-S for special and critical service.
