What is PCTFE and why choose it?
PCTFE (also named polychlorotrifluoroethylene, alias Kel-F / Neoflon) is a melt-processible fluoropolymer with ultra-low moisture permeability and excellent dimensional stability. As a transparent barrier polymer, PCTFE can be made into film, resin, sheet, and custom shapes. It meets FDA, ISO, and RoHS standards in many grades. At Peflon, we offer over a decade of PCTFE manufacturing experience with GMP clean production lines and multiple production lines in China. Our strengths include custom formulation, strict QA testing, full data sheet support, and fast global logistics. For pharmaceutical, cryogenic, or semiconductor use, PCTFE from Peflon ensures stable barrier, mechanical reliability, and supply security — request a quote today.
