For inventory control purposes, product name may be followed by an X. Products labeled PFA 950HP Plus and PFA 950HP Plus X are equivalent,  and all information in this document is applicable to both. 

Typical Applications  

With an exceptional typical MIT folding endurance of 2,500,000* cycles,  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 noncontaminating 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 exceptional chemical, permeation, 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.
