Chemours Teflon™ AF 2400 Amorphous Fluoropolymer Solutions
Categories:	Polymer; Thermoplastic; Fluoropolymer
Material Notes:	Teflon™ AF is a family of amorphous fluoropolymers similar to other amorphous polymers in optical clarity and mechanical properties, including strength, but also perform like fluoropolymers in their performance over a wide range of temperatures, outstanding electrical properties, and chemical resistance. Teflon™ AF solutions are made of Teflon™ AF amorphous fluoropolymer dissolved in Fluorinert® FC-40. Products labeled AF 2400 and AF 2400 X are equivalent . Information provided by Chemours.
