Daikin America Fluoroelastomers

Bisphenol Curable Copolymers

Daikin bisphenol curable copolymers are 66% fluorine content copolymers of hexafluoropropylene and vinylidene fluoride. These products exhibit the best heat resistance and lowest compression set among the DAI-EL family. They are particularly suited for O-ring and oil seal applications in high-heat environments. Daikin offers injection and compression molding grades, extrusion grades, metal adhesion grades, and compression set resistant grades. Most DAI-EL copolymers are supplied as cure incorporated precompound but specifically labeled base polymers (BP) are available. These require the addition of a bisphenol curing agent and an accelerator.
