Products labeled PFA 940HP Plus and PFA 940HP Plus X are equivalent and all information in this document is applicable to both.

 

Typical Application

With a typical MIT folding endurance of 300,000* cycles, PFA 940HP Plus is designed to withstand repeated flexing and aggressive chemical stress-cracking agents. Applications for PFA 940HP 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

PFA 940HP Plus is a premium fluoroplastic resin available in pellet form.  PFA 940HP Plus possess-es 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 300,000*) and chemical stress-crack resistance.  PFA 940HP 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 withPFA 940HP 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 PFA 940HP Plus.

 

This special purpose resin has a relatively high melt flow rate (typical MFR of 16), which permits higher extrusion speed and easier processing. The enhanced resistance to environmental stress-cracking makes  PFA 940HP Plus a preferred resin when extended service is required in hostile environments involving chemical, thermal, and mechanical stress. Additionally, the enhanced purity of  PFA 940HP 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. PFA 940HP Plus combines the processing ease of conventional thermoplastics with the properties similar to those of polytetrafluoroethylene.

 

With  PFA 940HP 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 PFA 940HP Plus can reduce contamination to protect process yields.

 

Properly processed products made from neat PFA 940HP 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 PFA 940HP 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.

 

PFA 940HP Plus meets the requirements of ASTM D3307, Type IV
