PFA, or perfluoroalkoxy, is well recognized for its ability to maintain mechanical integrity in extreme temperatures even when exposed to caustic chemicals. PFA comes in high purity versions that are SEMI F-57 certified, lending itself to critical fluid transport tubing applications that demand a very low level of extractables. This fluoropolymer possesses the ability to withstand temperature environments of up to 260°C/500°F and can be extruded in convoluted tubing forms that provide a highly flexible conduit.
The qualities of PFA include excellent lubricity, clarity, flexibility, and chemical resistance. This versatility has led to PFA being a popular material selection in the semiconductor, chemical, oil & gas, aerospace, automotive, pharmaceutical, fiber optics and medical industries.
Zeus offers a wide range of standard size products and precision custom extruded products made from fluoropolymers.

Aerospace: PFA is used to extrude convoluted tubing that serves as a flexible conduit to protect wires, cables and fiber optics from abrasion due to its mechanical integrity. The resin can be utilized in tubing form for fluid transfer applications that require excellent chemical resistance or air passage. PFA is non-flammable and resilient in a wide range of temperatures, ranging from low temperature to 500ºF (260ºC).
Automotive: PFA is excellent for wire harness insulation due to its dielectric strength. It is also very lubricious, providing dry lubrication solutions for a variety of applications. The resin can stand up to wide temperature variances with a working temperature range of up to 500ºF (260ºC). PFA is chemically resistant for critical fluid transfer, possesses UV resistance and can be produced in a variety of shapes and customized options.
Critical Fluid Transfer: The chemical resistance, mechanical integrity and high maximum temperature resistance of PFA are ideal for critical fluid transfer. It can handle a wide range of acids, bases and solvents. PFA HP is a SEMI F-57 certified material, making it an excellent selection for semiconductor clean room applications that require a high degree of purity and low metallic contamination. Zeus produces Double Containment Tubing with a PFA inner tubing and a FEP outer tube for enhanced security while transferring caustic fluids.
Electrical: PFA provides great electrical insulation (Dielectric Strength: 2000 volts/mil) as well as chemical resistance. These attributes serve it well in multiple extruded forms at high continuous service temperatures up to 500ºF (260ºC).
Fiber Optics: The chemical intertness of PFA provides a perfect jacketing material for easily sliding over fiber optics without damaging the delicate fibers. The material is UV and chemically resistant while having the ability to operate in a variety of extremes temperatures up to 500ºF (260ºC). PFA can be chemically etched to offer accelerated bonding ability. This material can also be formed into shapes and multi-lumens, allowing multiple channels of fibers to be encapsulated in one OD. Our PFA Convoluted Tubing acts as a flexible conduit that often houses and protects delicate fibers.
General Industrial: PFA is a highly lubricous fluoropolymer, positioning it as an ideal material for analytical and chemical transfer applciations. PFA has a unique combination of characteristics that allow it to be manufactured in long continuous lengths for air sampling technologies.; These qualities allow PFA tubing to support instrumentation and won’t degrade when exposed to caustic chemicals.
Oil & Gas: PFA has excellent heat resistance at working temperatures of up to 500ºF (260ºC). The material is also a good insulator when manufactured as a tube or custom shaped for slot liner applications. The material also can be made into a heat shrinkable form for specialized battery pack or rock core encapsulation applications due to its clarity, chemical and temperature resistance.
Medical: PFA is a highly lubricious fluoropolymer that can be manufactured in a variety of extruded products including custom sizes, profiles, and multi-lumens. PFA may be sterilized using gamma, EtO, e-beam, or autoclave sterilization which makes it a versatile material in medical applications. In addition, PFA can be sourced with flares, flanges, draw downs, drilled holes, or a combination of more than one Optimized Tubing Solution.
