FEP is a melt processable fluoropolymer that is used in various applications. It is a copolymer of hexafluoropropylene and tetrafluoroethylene that can be processed using conventional thermoplastics processing equipment. The end product is known for its outstanding physical, chemical and electrical properties and for its unique flame resistance.

It is also a versatile, cost-effective and corrosion-resistant polymer. It is ideal for a wide range of applications including electronics, medical devices, and environmental monitoring equipment.

PTFE is a popular choice for many applications and is one of the oldest synthetic fluoropolymers. It has many properties that make it a good choice for a variety of applications from coatings to automotive parts and appliances.

PFA is another popular option and combines some of the best characteristics of PTFE and FEP into one material. It is a much easier to mold than PTFE and has superior flow, creep resistance and thermal stability.

A very clear polymer, it has a lower heat shrink temperature than PTFE and is more flexible. It is also easier to form and can be tipped, tapered, flared and flanged.

TEFLON® FEP resins are available in pelletized form, and they work well with conventional melt extrusion techniques as well as injection-, compression-, transfer-, and blow-molding processes. They are compatible with many metalized, plasticized and epoxy coatings.

They are a great material for constructing wire and cable assemblies. They have excellent low temperature toughness and can be welded in place with minimal speed through a spin welding technique [62].

Whether it is wire, coaxial cable or technical gear that you need to protect, it is a good idea to choose a material that is highly resistant to chemicals as well as UV light. Choosing the right material can be a challenge. It is important to understand the differences between PTFE, FEP and PFA so that you can choose the best material for your needs.
