AFLAS™ FEPM - Usage

O-rings for Semiconductor Manufactuaring

Used in semiconductor manufacturing processes where resistance to harsh chemicals and high purity is required. AFLAS™ exhibits excellent resistance to plasma and chemicals, making it suitable for semiconductor process equipment

O-rings for Steam Resistance

FKM will harden if it comes into contact with steam which contains anti-corrosive agents, even if only a very small amount. AFLAS™ has excellent steam resistance and has proven extremely reliable in this application.

Cable Application

AFLAS™ dipolymers show excellent electrical properties and heat resistance. AFLAS™ is widely used for heat resistant rubber cable in automobiles, trains and electric appliances.

O-rings for downhole applications

O-rings are exposed to corrosive gas like sour gas (H2S), high temperature steam or basic mud in downhole applications. Rubber parts made from AFLAS™ survive longer under these harsh conditions.

Seals for Food & Beverage Lines and Bottles

AFLAS™, offers excellent resistance to both alkaline detergents and steam, ensuring safe use in such environments. Additionally, AFLAS™ has minimal odor and taste transfer, making it ideal for applications in food and beverage production lines, containers, and drink bottles—as well as for use in seals and gaskets.

O-rings for mechanical seals

O-rings in mechanical seals are required to be withstand exposure to various chemicals. AFLAS™ has superior chemical resistance compared to FKM. *The illustration above depicts a dual seal made by CHESTERTON.

O-rings for marine engines

Coolant inside large diesel engines contains anti-corrosive additives and some of these can damage FKM. Because of this, the higher cost product, FFKM, is sometimes used. However it is known that leakage problems can occur due to its poor elasticity. AFLAS™ has similar chemical resistance to FFKM and better elasticity than FFKM. AFLAS™ not only has a cost advantage but also a longer service life.

Transmission Seals for automotive

AFLAS™ has excellent chemical resistance against additives in engine oils, transmission oils and heat resistant greases. FKM hardens in these fluids, but AFLAS™ maintains its elasticity for longer.

Turbocharger Hoses

The excellent chemical resistance of AFLAS™ also makes it an outstanding material for hose applications. In particular, when the interior is exposed to liquids or gases containing alkaline or amine-based chemicals, conventional rubber materials such as FKM may not be sufficient—however, AFLAS™ can handle such conditions without any problem.

Oil Seals

Engine oils for automobiles often contain amine-based additives. AFLAS™ offers excellent durability even in high-temperature engine oils.
