DAI-EL

Daikin’s DAI-EL fluoroelastomer and perfluoroelastomer products provide excellent high temperature and aggressive fluid resistance in sealing and fluid transport applications for automotive, oil and gas, aerospace, chemical process, small engine, and other harsh sealing environments.

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.
