DAI-EL™G-550-Series/G-600-Series(Bisphenol Cure System/Ter-polymer)

G-550/G-600 are terpolymers of vinylidenfluoride /tetrafluoroethylene /hexafluoropropylene,and accelerator (bisphenol AF) and accelerator agent are incorporated.

This series possesses the best chemical resistance of all DAI-EL products, and is best-suited for fuel hose and sealing materials of chemical plants.

Grades and Features of G-550 Series/G-600 Series

G-550-Series

Grades	Fluorine Content(%)	Mooney viscosity (ML1+10 : 100℃)	Features	Technical data sheet
G-557	69.0	43	Good extension	-
G-558	69.0	43	Excellent fuel permeation Excellent extrudability
G-551	68.5	80	Good balance between solvent resistance and low-temperature flexibility

G-600-Series

Grades	Fluorine Content(%)	Mooney viscosity (ML1+10 : 100℃)	Features	Technical data sheet
G-671	66.0	60	Good low-temperature sealing
G-603	70.5	54	Excellent solvent resistance Good mold flow
G-621	70.5	88	Excellent solvent resistance

* In G-550/G600 Series, in accordance of increase of amount of fluorine content in polymer, chemical resistance and oil resistance improve, but resistance of compression set resistance and low-temperature performance reduced compared to G-700 series.
