Perfluoroalkoxy (PFA) and its high-performance counterpart, UL Listed PFAH (Perfluoroalkoxy High Temperature), have revolutionized wire and cable technology across multiple industries. These advanced fluoropolymers excel in extreme environments, making them indispensable for demanding applications. UL Listed Type PFAH wire, in particular, is a robust solution engineered for the harshest conditions, showcasing PFA’s unique capabilities. At Aerospace Wire and Cable, we take pride in delivering these exceptional products with rapid lead times, flexible minimum order quantities (MOQs), and expert support. Empowering industries worldwide to meet their unique demands efficiently.
The Evolution of PFA: Advancements in Fluoropolymer Technology
The discovery of PFA marked a pivotal advancement in fluoropolymer technology. Scientists seeking to overcome the processing challenges of Polytetrafluoroethylene (PTFE) discovered PFA as an innovative solution. This material combines PTFE’s desirable properties—such as high-temperature resistance and chemical inertness—with enhanced processability. Building upon the strengths of Fluorinated Ethylene Propylene (FEP) while addressing its limitations, PFA offers the following benefits:
- Enhanced melt processability compared to PTFE
- Exceptional temperature range: −80°C to 250°C
- Outstanding resistance to chemicals, fluids, and UV exposure
- Low friction coefficient for easier installation
- Excellent mechanical strength

PFAH: UL Rated Excellence for Demanding Applications
UL Listed PFAH takes the benefits of PFA further. This UL-certified material complies with rigorous standards, ensuring reliability in the most demanding environments. With a voltage rating of 600V and a temperature tolerance up to 250°C, PFAH wires are engineered to handle high-current loads
PFAH wires feature nickel-plated annealed copper conductors, which enhance conductivity and provide corrosion resistance. Additionally, PFAH insulation is 20% smaller in diameter than traditional braided cables, allowing for compact, space-saving installations.
Additionally, PFAH boasts a temperature rating 2.7 times higher than that of THHN wire.
Advantages over Traditional Materials
PFA and PFAH cables offer significant advantages over traditional materials like PVC and rubber. Their ability to operate at temperatures ranging from −80°C to 250°C makes them ideal for both cryogenic and high-heat environments. These materials also provide superior chemical resistance, maintaining integrity in harsh industrial settings where PVC and rubber would degrade. PFA and PFAH cables are compact, lightweight, and durable, offering a longer lifespan, reduced maintenance needs, and improved electrical performance. Their flame resistance further enhances safety, particularly in mission-critical systems. In essence, PFA and PFAH cables deliver the performance and reliability that traditional materials cannot match, making them the go-to choice for industries that demand the highest standards.
Applications of PFA and PFAH Insulated Cable and Wire
PFA and PFAH cables excel in environments where traditional materials fall short. Their exceptional thermal stability, chemical resistance, and mechanical strength make them indispensable for a wide range of applications. These include internal wiring for motors; cryogenic systems; load cells; electronic equipment; as well as booster melting systems and high-performance sensors. Additionally, PFA and PFAH cables are widely used in aerospace and automotive applications, such as spacecraft wiring, electric vehicle systems, and battery management.
