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.
