Poly[4,5-difluoro-2,2-bis(trifluoromethyl)-1,3-dioxole-co-tetrafluoroethylene] Chemical Properties,Uses,Production

Uses

Optoelectronic devices for optical clarity, low-refractive index coating for optical devices, protective coating for chemical resistance, release coating, and sight window for harsh chemical environments.

General Description

Poly(4,5-difluoro-2,2-bis(trifluoromethyl)-1,3-dioxole-co-tetrafluoroethylene)(AF2400) is a fluorinated polymer that formed by copolymerization of 4,5-difluoro-2,2-(trifluoromethyl)-1,3-dioxole(PDD) and tetrafluoroethylene(TFE). It has a relatively high glass transition temperature(T_g) and optical transparency which allows it be a photo-stable polymer that can be used for a wide range of coating application in electronic and electrochemical industry.
