PCTFE (Polychlorotrifluoroethylene) is a homopolymer of chlorotrifluoroethylene. Features of PCTFE include high compressive strength and low deformation under load. In particular, its cold flow characteristic is lower than other fluoropolymers and it does not deform under load at room temperature. PCTFE has extremely low gas permeability and essentially does not absorb moisture. PCTFE is known by the trade name of Kel-F® 81. This was produced by 3M but has been discontinued since December of 1995. Currently, PCTFE resin is produced by Daikin, under the trade name Neoflon®. Specifications: ASTM D-1430-95 TYPE 1, GRADE 3; AMS 3650 (except 3.2) FDA Reg. 21-CFR-177.2600.
