Typical Application
With an exceptional typical MIT folding endurance of 2,500,000* cycles, DuPont™ Teflon ® PFA 950HP Plus is designed to withstand repeated flexing and the most aggressive chemical stress-cracking agents. Applications for Teflon ® PFA 950HP 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.

Description
Teflon ™ PFA 950HP Plus is a premium fluoroplastic resin available in pellet form. Teflon ™ PFA 950HP 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 and chemical stress-crack resistance. Teflon ™ PFA 950HP 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 950HP Plus have improved clarity and a smooth finish, which can further help prevent buildup of microbial contamination in water handling systems. Table 1 shows the typical property data for Teflon ™ PFA 950HP Plus.

Teflon ® PFA 950HP Plus is a relatively low melt flow rate (typical MFR of 2), special purpose resin with the lowest level of extractables designed to meet ultra-high purity requirements. The enhanced resistance to environmental stress-cracking makes Teflon ® PFA 950HP Plus a preferred resin when extended service is required in hostile environments involving chemical, thermal, and mechanical stress. Additionally, the enhanced purity of Teflon ® PFA 950HP Plus makes it suitable for applications that require improved color, lower 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. Examples are in semiconductor manufacture, fluid handling systems for industry or life sciences, and instrumentation for precise measurements of fluid systems. Teflon ® PFA 950HP Plus combines the processing ease of conventional thermoplastics with the properties similar to those of polytetrafluoroethylene.

With Teflon ® PFA 950HP Plus, components can last longer under dynamic loads and resist damage caused by ozonated fluids and fluorosurfactants. Combined with exceptionalchemical, ermeation, and stress-crack resistance, this durability leads to a reduced cost of ownership. The high purity and fully fluorinated molecule end groups of Teflon ® PFA 950HP Plus can reduce contamination to protect process yields.

Properly processed products made from neat Teflon ® PFA 950HP Plus resin provide the superior properties characteristic of fluoroplastic resins: chemical inertness, exceptional dielectric properties, heat resistance, toughness and flexibility, low coefficient of friction, non-stick characteristics, negligible moisture absorption, low flammability, performance at temperature extremes, and excellent weather resistance.

In a flame situation, products of Teflon ® PFA 950HP Plus resist ignition and do not promote flame spread. When ignited by flame from other sources, their contribution of heat is very small and added at a slow rate with very little smoke.

Teflon ® PFA 950HP Plus meets the requirements of ASTM D3307, Type V
