DAI-EL 80XX/90XX Properties & Benefits
Daikin’s DAI-EL Peroxide Curable grades come as copolymers with 66% fluorine content and terpolymers with between 67% and 71% fluorine content.
Compared to the bisphenol cured grades, they have better acid and solvent resistance and better overall mechanical properties.
All grades are available as NFS FKM – no fluorinated emulsifiers used.
Properties
Non-fluorinated emulsifier (NFS)
Heat / Steam resistance
Fuel resistance
Oil resistance
Acid resistance
Benefits
Production in France
Suited for turbocharger hoses, o-rings, oil seals and diagphragms in high-heat environments
Peroxide curable
No post-curing necessary
The trade-off is a reduction in heat and compression set resistance compared to the bisphenol cured grades.
In cases where higher base resistance is needed, the DAI-EL BRE range of products can be an option.
Special Low-Temperature grades are available.
