Chemours Teflon PFA 350T-J ( 350TJ) Fluoroplastic resin

Applications for Teflon™ PFA 350T-J include extruded tubing or hose for handling aggressive fluids at high pressures; chemical linings for pipes, valves, and fittings used in the chemical processing industries; film for high flex service; and traditional extruded or molded articles requiring the unique performance of Teflon™ PFA.

Description
Teflon™ PFA 350T-J is a premium resin available in clear 2.5 mm pellets. This resin is a chemically modified form of Teflon™ PFA 350 that combines many of the benefits of the parent resin with several new ones. The additional benefits are improved color, improved thermal stability, and better mold release characteristics. Similar to Teflon™ PFA 350, this resin has a relatively low melt flow rate, high flex life, and enhanced resistance to environmental stress cracking, compared to most grades of Teflon™ PFA.

These additional benefits make Teflon™ PFA 350T-J an ideal resin in applications like transfer molding, where the resin is exposed to high temperatures and long hold-up times.

Teflon™ PFA 350T-J is preferred when extended service is required in hostile environments involving chemical, thermal, and mechanical stress. Compared to other fluoropolymers, its creep resistance at high service temperature provides a superior balance and level of end use properties.

Properly processed products made from virgin Teflon™ PFA 350T-J resin provides the superior properties typical of fluoropolymer resins: retention of physical properties after service at 260 °C, useful properties at -196 °C, 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 made of Teflon™ PFA 350T-J resist ignition and do not themselves promote flame spread. When ignited by flame from other sources, the contribution of heat is very small and added at a slow rate with very little smoke. Teflon™ PFA 350T-J meets the requirements of ASTM D3307, Type II.
