Chemours Teflon® PFA Grade 950 HP Plus Extrusion and Molding Resin
Categories: Polymer; Thermoplastic; Fluoropolymer; Perfluoroalkoxy (PFA)

Material Notes: DuPont™ Teflon® PFA HP Plus fluoropolymer is a special purpose resin available in clear, 2.5-mm (0.1 in) pellets. This resin is similar to PFA HP with the additional benefits of improved flex life and chemical stress crack resistance. Teflon® PFA HP Plus meets the increasingly stringent requirements for ultra-reliable and non-contaminating parts, while retaining the same exceptional chemical resistance, high purity and protection against ionic contamination as PFA HP. 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. Parts molded with Teflon® PFA HP Plus have improved clarity and a smooth finish, which can further help prevent buildup of microbial contamination in water handling systems.

The exceptional purity of Teflon® PFA HP Plus makes it suitable for applications that require low extractable fluorides, and freedom from other foreign materials. This product contains no additives and is designed for hostile chemical environments where purity in the parts-per-billion range is needed. An example is in fluid handling systems for the manufacture of semiconductors. Teflon® PFA HP Plus is preferred when extended service is required in hostile environments involving chemical, thermal, and mechanical stress. Table 1 shows the typical property data for Teflon® PFA HP Plus.

The excellent thermal stability of Teflon® PFA HP Plus results in better moldings and reduces metal pickup from processing equipment. Teflon® PFA HP Plus combines the processing ease of conventional thermoplastics with the properties similar to those of polytetrafluoroethylene.

Properly processed products made from Teflon® PFA HP Plus resin provide the superior properties typical of fluoropolymer resins; retention of properties after service at 250°C (482°F), useful properties at –196°C (–320°F), and chemical inertness to nearly all industrial chemicals and solvents. Dielectric properties are excellent. Molded products have moderate stiffness and high ultimate elongation.

In a flame situation, products of Teflon® PFA HP Plus resist ignition and do not themselves promote flame spread. When ignited by flame from other sources, their contribution to heat is very small and added at a slow rate with very little smoke.


Applications for Teflon® PFA HP Plus include tubing; pipe, fittings, valves, and other components for ultrapure fluid handling systems, either unsupported or for linings.

Chemours was formed from former DuPont performance chemicals businesses, including DuPont Fluoroproducts, in 2015.
