Fluoroelastomers DAI-EL™

DAI-EL Fluoroelastomers are high-performance synthetic rubber which have outstanding heat resistance, oil resistance, compression set resistance, acid resistance, and solvent resistance.

Main applications are engine shaft sealing for automotive which utilizes good heat resistance and oil resistance as well as o-ring, packing, and hoses. It also utilizes small amount of outgas for semiconductor fields and used on wires and its peripheral parts with using electric insulation. Also recently from the viewpoint of environmental problems, low-gas transparency is being required.

Grades and features of fluoroelastomer (DAI-EL™)

■ General Grade

selection guide (PDF)

* In order to achieve maximum performance, application specific selection is neccessary. Depending on difference of cure system and polymer structure, its characteristics can be adjusted to some extent. So by making selections applicable to its purpose and processing method, the performance of DAIEL can be exerted considerably. For your reference to select DAI-EL, please see "selection guide."
