General Purpose Fluoropolymer PFA Resin With Excellent Thermal Resistance

PFA (Or Perfluoroalkoxy) Is A Fluoropolymer With Excellent Thermal And Chemical Resistance.

Overview of PFA (Perfluoroalkoxy) Fluoropolymers

PFA (Perfluoroalkoxy) fluoropolymers are high-performance materials available in pellet and powder forms. Known for their exceptional thermal and chemical resistance, PFAs share similar properties with other fluoropolymers such as PTFE and FEP, including a low coefficient of friction, non-stick characteristics, and chemical inertness.

Key Features

1. Thermal Resistance:
   • PFA can withstand a wide temperature range from -200ºC to 260ºC. Its high-temperature stability makes it suitable for various high-temperature applications.
   • PFA maintains stability at high processing temperatures, making it ideal for demanding industrial conditions.
2. Chemical Resistance:
   • PFA is highly resistant to a variety of chemicals, making it excellent for use in corrosive environments.
   • It is particularly suitable for applications that require prolonged exposure to chemicals, such as chemical processing equipment and piping.
3. UV Resistance:
   • PFA resists degradation from UV light, ensuring long-term performance in outdoor applications.
   • This characteristic gives PFA a significant advantage in outdoor and sun-exposed environments.
4. Mechanical Strength:
   • PFA offers higher melt strength, excellent crack and stress resistance.
   • Compared to FEP, PFA has more than ten times the flex life, making it exceptional for applications requiring high mechanical strength and durability.
5. Electrical Properties:
   • PFA has a low dielectric constant, making it ideal for semiconductor manufacturing and various electrical applications.
   • This low dielectric property provides a significant advantage in environments requiring electrical insulation.

Applications

1. Coatings:
   • PFA coatings provide extended service life in environments with chemical, thermal, and mechanical stress.
   • Commonly used for equipment and surfaces requiring high corrosion and heat resistance.
2. Molding:
   • As a thermoplastic resin, PFA can be extruded, injection molded, blow molded, and transfer molded.
   • Typical applications include tubing, containers, linings, and wire coatings.
   • Its excellent processing performance makes it suitable for manufacturing complex shapes and high-precision products.
