Description

Description

Fluoroelastomer 23702, which is comprised of vinylidene fluoride (VF2) and Chlorotrifluoroethylene (CTFE), have high thermal resistances. Decomposition temperature is above 300°C and can resist to prolongated heating at 200°C without change of mechanical strength or elasticity. Frequently used where chemical resistances is required. It has excellent flow ability. It is resistant to oils, fuels, and other organic solvents. It is dissolved in esters, ketones and is swelling in aromatic hydrocarbon and some other solvents.
