Typical Application
With a typical MIT folding endurance of 300,000* cycles, DuPont™Teflon ® PFA 940HP Plus is designed to withstand repeated flexingand aggressive chemical stress-cracking agents. Applications forTeflon ® PFA 940HP Plus include fluid handling components forhigh-performance chemical delivery systems, as well as tubing,unsupported pipe linings for the production of ultra-purechemicals, and semiconductor components where purity in theparts-per-billion range is critical.

Description
DuPont™ Teflon ® PFA 940HP Plus is a premium fluoroplastic resinavailable in pellet form. Teflon ® PFA 940HP Plus possess-es thesame exceptional chemical resistance, high purity, and protectionagainst ionic contamination as Teflon ® PFA HP grades with theadded benefits of improved flex life (typical MIT flex of 300,000*)and chemical stress-crack resistance. Teflon ® PFA 940HP Plus meetsthe increasingly stringent requirements for ultra-reliable andnon-contaminating parts, as well as unmatched HCl permeationresistance. The improved flex life and chemical resistance willreduce the cost of ownership of high purity fluid handling systemsby reducing downtime caused by mechanical or chemical stresses.Additionally, parts molded with Teflon ® PFA 940HP Plus haveimproved clarity and a smooth finish, which can further helpprevent buildup of microbial contamination in water handlingsystems. Table 1 shows the typical property data for Teflon ® PFA940HP Plus.

This special purpose resin has a relatively high melt flow rate(typical MFR of 16), which permits higher extrusion speed andeasier processing. The enhanced resistance to environmentalstress-cracking makes Teflon ® PFA 940HP Plus a preferred resinwhen extended service is required in hostile environments involvingchemical, thermal, and mechanical stress. Additionally, theenhanced purity of Teflon ® PFA 940HP Plus makes it suitable forapplications that require improved color, lower extractablefluorides, and freedom from other foreign materials. This productcontains no additives and is designed for hostile chemicalenvironments where purity in the parts-per-billion range is needed.Examples are in semiconductor manufacture, fluid handling systemsfor industry or life sciences, and instrumentation for precisemeasurements of fluid systems. Teflon ® PFA 940HP Plus combines theprocessing ease of conventional thermoplastics with the propertiessimilar to those of polytetrafluoroethylene.

With Teflon ® PFA 940HP Plus, components can last longer underdynamic loads and resist damage caused by ozonated fluids andfluorosurfactants. Combined with excellent chemical, permeation,and stress-crack resistance, this durability leads to a reducedcost of ownership. The high purity and fully fluorinated moleculeend groups of Teflon ® PFA 940HP Plus can reduce contamination toprotect process yields.

Properly processed products made from neat Teflon ® PFA 940HP Plusresin provide the superior properties characteristic offluoroplastic resins: chemical inertness, exceptional dielectricproperties, heat resistance, toughness and flexibility, lowcoefficient of friction, non-stick characteristics, negligiblemoisture absorption, low flammability, performance at temperatureextremes and excellent weather resistance.

In a flame situation, products of Teflon ® PFA 940HP Plus resistignition and do not promote flame spread. When ignited by flamefrom other sources, their contribution of heat is very small andadded at a slow rate with very little smoke.

Teflon ® PFA 940HP Plus meets the requirements of ASTM D3307, TypeIV
