Chemours Teflon™ PFA 945HP Plus Premium fluoroplastic resin
Categories:	Polymer; Thermoplastic; Fluoropolymer; Perfluoroalkoxy (PFA); Polyperfluoroalkoxyethylene, Molded/Extruded
Material Notes:	Teflon™ PFA 945HP Plus is a premium fluoroplastic resin available in pellet form. Teflon™ PFA 945HP Plus possesses the same exceptional chemical resistance, high purity, and protection against ionic contamination as Teflon™ PFA HP grades with the added benefits of improved flex life (typical MIT flex of 800,000) and chemical stress-crack resistance. Teflon™ PFA 945HP Plus meets the increasingly stringent requirements for ultra-reliable and non-contaminating parts, as well as unmatched HCl permeation resistance. The improved flex life and chemical resistance will reduce the cost of ownership of high purity fluid handling systems by reducing downtime caused by mechanical or chemical stresses. Additionally, parts molded with Teflon™ PFA 945HP Plus have improved clarity and a smooth finish, which can further help prevent buildup of microbial contamination in water handling systems. With a typical MIT folding endurance of 800,000 cycles, Teflon™ PFA 945HP Plus is designed to withstand repeated flexing and aggressive chemical stress-cracking agents. Applications for Teflon™ PFA 945HP Plus include fluid handling components for high-performance chemical delivery systems, as well as tubing, unsupported pipe linings for the production of ultra-pure chemicals, and semiconductor components where purity in the parts-per-billion range is critical.
