340 | Extrusion and injection molding resin. Highest flow rate. Lowest molecular weight. | Tubing Injection or blow-molded articles Chemical linings (tanks, pipes, valves, pumps) |
345 | Extrusion and injection molding resin. Intermediate flow rate with higher stress crack resistance than 340. | Tubing Injection- or blow-molded articles Chemical linings |
350 | High molecular weight resin with highest resistance to stress cracking. Lowest flow rate of this series of resins for extrusion and transfer molding. | Films Chemical tank linings Molded articles Tubing |
Teflon® PFA Grade | Ultrahigh Purity | Applications |
416HP | Special-purpose resin with higher melt flow rate than most other PFA resins. This permits higher extrusion speed and easier processing, making this a cost-effective alternative for producing thin-wall and complicated articles. Additional benefits are enhanced purity and thermal stability while processing. | • High performance thin-wall wire coatings; tubing or pipe linings for production of ultrapure chemicals; semiconductor components and fluid handling systems for high performance chemical filters. |
440 HP | Premium resin with the lowest level of extractables designed to meet ultrahigh purity requirements. Highest flow rate for injection molding and extrusion processes. FDA food contact compliance. Highest level of inertness due to stable end group polymer structure. | Fluid handling components for critical, high-purity processes like semiconductor, pharmaceutical, and biotechnology |
450 HP | Premium high molecular weight resin designed to meet ultrahigh purity requirements. Highest level of stress crack resistance. For extrusion and transfer molding processes. FDA food contact compliance. | Fluid handling components for critical, high-purity processes like semiconductor, pharmaceutical, and biotechnology |
451HP | Special-purpose resin that offers the benefits of PFA 350 with the additional benefits of enhanced purity and improved thermal stability while processing. This resin has a relatively low flow rate, high flex life and enhanced resistance to environmental stress cracking. 451HP is a grade with improved surface smoothness achieved by minimizing spherulite size, and enhanced chemical permeation resistance. | • Tubing; unsupported pipe or pipe linings for production of ultrapure chemicals; semiconductor component handling systems and fluid handling components. |
940 HPPlus | Special-purpose resin with the exceptional purity of PFA 440 HP, with improved flex life and chemical stress crack resistance. | Applications requiring low extractable fluorides and freedom from other foreign materials Molded parts Tubing |
950 HPPlus | Special-purpose resin with exceptional purity. Similar to PFA 450 HP, with improved flex life and chemical stress crack resistance. | Applications requiring low extractable fluorides and freedom from other foreign materials. |
Teflon® PFA Grade | Special Purpose | Applications |
TE-7224 | Dispersion composed of approximately 60% PFA resin dispersed in water. Contains a nonionic wetting agent and stabilizer. | General-purpose product used in a variety of coating applications, such as heat sealable topcoats |
