產(chǎn)品說明:
DuPont? Teflon? PFA 440 HP fluoropolymer is a special purposeresin available in clear, 2.5-mm (0.1-in.) pellets. This resin is achemically modified form of Teflon? PFA 340 that combines many ofthe benefits of the parent resin with several new ones. Theadditional benefits may include enhanced purity, improved thermalstability while processing, and chemical inertness, for example, toozonated fluids.
The enhanced purity of Teflon? PFA 440 HP makes it suitable forapplications that require improved color, lower extractablefluorides, and freedom from other foreign materials. This productcontains no additives and is designed for hostile chemicalenvironments where purity in the parts-per-billion range is needed.Examples are in semiconductor manufacture, fluid handling systemsfor industry or life sciences, and instrumentation for precisemeasurements of fluid systems.
The improved thermal stability of Teflon? PFA 440 HP results inreduced amounts of bubbles in final parts and decreased corrosionof processing e Teflon? PFA 440 HP combines the processingease of conventional thermoplastics with properties similar tothose of polytetrafluoroethylene. Properly processed products madefrom neat Teflon? PFA 440 HP resin provide the superior propertiestypical of fluoropolymer resins: retention of properties afterservice at 260°C (500°F), useful properties at –196°C (–320°F), andchemical inertness to nearly all industrial chemicals and solvents.Dielectric properties are excellent. Molded products have moderatestiffness and high ultimate elongation.
Three categories (A, B, and D) of Teflon? PFA 440 HP resincovering a broad range of melt flow rates (MFR) are available. Thelow MFR resin provides a higher degree of stress crack resistancewhile the high MFR resin is easier to process. In a flamesituation, products of Teflon? PFA 440 HP resist ignition and donot themselves promote flame spread. When ignited by flame fromother sources, their contribution of heat is very small and addedat a slow rate with very little smoke.
Statements, or data, regarding behavior in a flame situation arenot intended to reflect hazards presented by this or any othermaterial when under actual fire conditions.
Applications
Applications for Teflon? PFA 440 HP include tubing; unsupportedpipe or pipe linings for production of ultrapure chemicals;semiconductor component and fluid handling systems forhighperformance chemical filters.
Chemours was formed from former DuPont performance chemicalsbusinesses, including DuPont Fluoroproducts, in 2015.
