DuPont Teflon® PFA Grade 345T Extrusion and Molding Resin for High Temperature Applications

 

Subcategory: Fluoropolymer; Thermoplastic; PFA

Key Words: DuPont Fluoroproducts; DuPont PFA

Material Notes:
Teflon® PFA345T us a special-purpose resin available in clear, 2.5mm (0.1in) pellets. This resin is a chemically modified form of Teflon® PFA 345 that combines many of the benefits of the parent resin with several new ones. Like Teflon® PFA345, it offers great flex life and resistance to environmental stress cracking. The additional benefits are improves thermal stability and color while processing.

The improved thermal stability of Teflon® PFA 345T results in reduced amounts of bubbles in final parts and decreased corrosion of processing equipment. This resin can be processed at higher temperatures and higher rated than Teflon® PFA345. Teflon® PFA345T combines the processing ease of conventional thermoplastics with properties similar to those of polytetrafluoroethylene. Properly processed products made from Teflon® PFA345T resin provides the superior properties typical to fluoropolymer resins: retention of physical properties at -196°C (-320°F), and chemical inertness to nearly all industrial chemicals and solvents. Dielectric properties are excellent. Molded products have moderate stiffness and high ultimate elongation.

In a flame situation, products of Teflon® PFA345T resist ignition and no not themselves promote flame spread. When ignited by flame from other sources, the contribution of heat is very small and added at a low rate with very little smoke

Applications

Applications for Teflon® PFA345T include tubing, unsupported pipe linings for production of corrosive chemicals, and wire and cable insulation for chemical environments.
