AFLAS®

AFLAS® is unique fluoroelastomer that has superior amine resistance and electrical insulation compared to conventional fluoroelastomers.
AFLAS® is highly suitable for critical applications where exceptional reliability is required.

AFLAS® Functions and Features

Chemical resistance

AFLAS® is highly resistant to a wide range of chemicals, such as acids, amines/bases and steam.
AFLAS® has superior resistance to strong bases in comparison with FKM.

Heat resistance

The molecular structure of AFLAS® gives it outstanding heat-resistance allowing it to be used continuously at 200°C. Its exceptional heat-resistance even enables it to withstand temperatures of 250°C.

Low aromatizing properties

AFLAS® has extremely low aromatizing properties compared to other rubber materials. It can be considered extremely effective for use in gaskets and packing on piping components for production lines, where lingering or transferred smells are a concern.

AFLAS® Usage

Industrial applications where the numerous high-performance properties of AFLAS® fluoroelastomers could be of benefit include food processing, nuclear power generators, electrical fields, chemical plants, automobiles, machinery, and many others. It is widely used in crtitical applications that require a high reliability.

AFLAS® Usage

The following is an introduction of the major uses of AFLAS®.

O-rings and gaskets

O-rings and gaskets

AFLAS® has excellent heat resistance and chemical resistance, and is used for sealing parts for equipment in chemical plants, downhole applications, and food processing.

Wire and cable

Wire and cable

AFLAS® has superior electrical insulation properties, heat resistance and mechanical strength, which enables thinner wires for larger electrical currents.
Accordingly, AFLAS® was selected for the motor cables of the bullet train.

Oil seals

Oil seals

Oils and lubricants used in the automotive sector contain amine-based additives. AFLAS® is
used for oil seals resistant under the conditions of high temperatures.
