Typical Applications  

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.  

Description  

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. Table 1 shows the  typical property data for Teflon™  PFA 945HP Plus. 

This special purpose resin has a mid-range melt flow rate (typical MFR of  7), which permits relatively high extrusion speed and easier processing.  The enhanced resistance to environmental stress-cracking makes Teflon™ PFA 945HP 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 945HP 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 945HP Plus combines the processing ease  of conventional thermoplastics with the properties similar to those of  polytetrafluoroethylene. 

With Teflon™  PFA 945HP Plus, components can last longer under dynamic  loads and resist damage caused by ozonated fluids and fluorosurfactants.  Combined with excellent 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 HP Plus can  reduce contamination to protect process yields. 

Properly processed products made from neat Teflon™  PFA 945HP 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 945HP 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.
