DESCRIPTION
™ FLUOROPOLYMERS PROVIDE THE PERFECT SOLUTION FOR YOUR DESIGN NEEDS
The products and applications that depend on the characteristics of ™ fluoropolymers range from aerospace to energy, cookware to textiles, semiconductors to smart cities. Fluoropolymers address the myriad issues faced by manufacturers and processors.

Industrial products developed with ™ fluoropolymer coatings, resins, additives, or films have exceptional resistance to:
* High temperatures
* Chemical reactions
* Corrosion
* Stress cracking

The properties of ™ products make it the preferred solution for a host of industrial applications and processing techniques. As industrial manufacturing continues to thrive, the ongoing development of ™ fluoropolymers strengthen and reinforce the industry by:
* Increasing uptime
* Improving productivity
* Facilitating innovation

For inventory control purposes product name may be followed by an X.

Products labeled PFA 350 and PFA 350 X are equivalent and all information in this document is applicable to both.

Typical Application
Applications for DuPont™ ® PFA 350 include extruded tubing for use in handling aggressive fluids at high pressures; chemical linings for pipes used in the chemical processing industry; film for high flex service; and traditional extruded, injection-molded, or blow-molded articles requiring the unique performance of ® .

DuPont™ PFA 350 is a general-purpose fluoroplastic resin available in pellet form. Compared with other grades of ® PFA, its most unique features are a relatively low flow rate, greatly increased flex life, and enhanced resistance to environmental stress-cracking over both ® PFA 340 and 345 ( ® PFA 350 has a typical MIT folding endurance of 500,000*, compared to that of 15,000 and 50,000 for ® PFA 340 and 345 respectively). ® PFA 350 is preferred when extended service is required in hostile environments involving chemical, thermal, and mechanical stress. Table 1 shows the typical property data for ® PFA 350.

® PFA 350 is used when traditional extrusion and molding processes are required for producing products with the superior properties of a fluoroplastic resin. Compared to other thermoplastics, the high melt strength and thermal stability of ® PFA 350 can be used to improve processing rates. Compared with other fluoroplastics, creep resistance at high service temperatures provides a superior balance and level of end-use properties. ® PFA 350 combines the processing ease of conventional thermoplastics with many properties similar to those of polytetrafluoroethylene.

Properly processed products made from neat ® PFA 350 resin provide the superior properties characteristic of fluoroplastic resins: chemical inertness, exceptional dielectric properties, heat resistance, toughness and flexibility, low coefficient of friction, non-stick characteristics, negligible moisture absorption, low flammability, performance at temperature extremes, and excellent weather resistance.

In a flame situation, products of ® PFA 350 resist ignition and do not promote flame spread. When ignited by flame from other sources, their contribution of heat is very small and added at a slow rate with very little smoke.

® PFA 350 meets the requirements of ASTM D3307, Type III
