Products labeled PFA 440HPA and PFA 440HPA X are equivalent and all information in this document is applicable to both.

 

Typical Application

Applications for  PFA 440HPA include fluid handling components for critical, high-purity processes like semiconductor, pharmaceutical, and biotechnology, as well as applications where purity in the parts-per-billion range is needed.  PFA 440HPA offers a slightly higher melt flow rate than Teflon ® PFA 440HPB, providing greater processing ease.

 

Description

 PFA 440HPA is a special purpose fluoroplastic resin available in pellet form. This resin is a chemically modified form of Teflon ® PFA 340 that combines many of the benefits of the parent resin (a relatively high typical melt flow rate of 16) with several additional benefits including enhanced purity, improved thermal stability while processing, and chemical inertness, for example, to ozonated fluids. Table 1 shows the typical property data for PFA 440HPA.

 

PFA 440HPA is a premium resin with the lowest level of extractables designed to meet ultra-high purity requirements. PFA 440HPA has a relatively high melt flow rate (typical MFR of 16) for injection molding and extrusion processes, and the highest level of inertness due to stable end group polymer structure. The enhanced purity of TPFA 440HPA 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. Compared to other thermoplastics, the high melt strength and thermal stability of PFA 440HPA can be used to improve processing rates, combining the processing ease of conventional thermoplastics with many properties similar to those of polytetrafluoroethylene.

 

Properly processed products made from neat  PFA 440HPA 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 440HPA 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 440HPA meets the requirements of ASTM D3307, Type I
