Teflon PFA 440 HP fluoropolymer is a special-purpose resin available in clear, 2.5-mm(0.1-in.)pellets.
This resin is a chemically modified form of Teflon PFA 340 that combines many of the benefits of the parent resin with several new ones.
The additional benefits are enhanced purity and improved thermal stability while processing.
The enhanced purity of Teflon PFA 440 HP 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-bilion range is needed.
Examples are in semiconductor manufacture, fluid handling systems for industry or life sciences, and instrumentation for precise measurements of fluid systems.
The improved thermal stability of Teflon PFA 440 HP results in reduced amounts of bubbles in final parts and decreased corrosion of processing equipment.
Teflon PFA 440 HP combines the processing ease of conventional thermoplastics with properties similar to those of polytetrafluoroethylene. |
