DAI-EL Base Resistant Elastomers

For some automotive and oil & gas applications, the base resistance of fluoroelastomer (FKM) products is not sufficient. FEPM rubber has excellent base and amine resistance but has poor low temperature flexibility, poor fuel resistance, and slow cure speed compared to FKM. DAIKIN has developed Base Resistant Elastomers. These are 62% fluorine content polymers which combine the processing advantages of FKM with amine resistance comparable to FEPM. These products have excellent overall mechanical properties.

DESCRIPTION

Excellent characteristics

 - Base resistance
 - Coolant resistance
 - Excellent mechanical properties
 - Excellent anti-flex fatigue
 - Heat resistance (~200℃)
 - Engine / transmission oil resistance
 - Fuel resistance
 - Solvent resistance
 - Steam resistance
 - Acid resistance

Applications

They are particularly suited for turbo charger hose, o-ring, oil seal and diaphragm applications in high-heat environments.

Compression and injection molding.

These grades are peroxide curable and post curing can be eliminated if desired.
