For inventory control purposes, product name may be followed by an X. Products labeled PFA 416 HP and PFA 416 HP X are equivalent, and all  information in this document is applicable to both. 

Typical Applications  

Applications for Teflon™ PFA 416HP include high performance thinwall wire coatings; intricate injection molded parts for production  of chemicals where purity in the parts-per-billion range is needed;  semiconductor components and electronic parts; and fluid handling  systems for high performance chemical filters. With a typical melt  flow rate (MFR) of 42, Teflon™ PFA 416HP resin is ideally suited for  applications requiring a high processing speed and very low viscosity. 

Description  

Teflon™  PFA 416HP is a special purpose fluoroplastic resin available in  pellet form. This resin has a higher melt flow rate (typical MFR of 42)  than most other PFA fluoroplastic resins, which permits higher extrusion  speed and easier processing, making Teflon™  PFA 416HP a costeffective alternative for producing thin-wall and complicated articles.  

Unlike other high melt flow rate polymers, Teflon™  PFA 416HP is specially  formulated to provide a high melt flow rate for processing ease, while still  providing good flexural properties and stress-crack resistance. These  unique properties, coupled with the resin’s high thermal stability, enable  thin coatings of ultra-fine wires and injection molding of complex parts.  Table 1 shows the typical property data for Teflon™  PFA 416HP.  

The enhanced purity of Teflon™ PFA 416HP makes it suitable for  applications that require improved color, lower extractable fluorides, and  freedom from other foreign materials. Teflon™ PFA 416HP contains no  additives and is designed for hostile chemical environments where purity  in the parts-per-billion range is needed. Teflon™ PFA 416HP combines the  processing ease of conventional thermoplastics with many properties similar  to those of polytetrafluoroethylene. Compared to other thermoplastics, the  high melt strength and thermal stability of Teflon™ PFA 416HP can be used  to improve processing rates, and allows intricate electronics to be insulated  with an extremely thin coating and still withstand soldering. 

Properly processed products made from neat Teflon™  PFA 416HP resin  provide the superior properties typical of the 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 416HP 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.
