Typical Application
Applications for DuPont™ Teflon ® PFA 416HP include high performance thin-wall 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 of 42, Teflon ® PFA 416HP resin is ideally suited for applications requiring a high processing speed and very low viscosity.
Description
DuPont™ 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 cost-effective 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.
Teflon ® PFA 416HP meets the requirements of ASTM D3307, Type IX
