As far as the field of chemical engineering and material science is concerned, the discovery of FEP tubing was an incredible leap forward. It was the need of a more processable material that prompted engineers to explore more options and finally led to FEP’s discovery.
Technically, FEP is a copolymer of hexafluoropropylene and tetrafluoroethylene, with most properties of PTFE (Polytetrafluoroethylene). FEP is more flexible and offers lower heat shrink temperatures than PTFE.
It is produced by traditional processing techniques, such as injection molding, extrusion and film casting.

Benefits and Features of FEP Tubing

FEP film is a transparent thermoplastic film that can be heat sealed, heat bonded, thermoformed, welded and laminated with other materials.
All of the above fabrication properties combine with the following features and benefits to provided incredible manufacturing capabilities:

Incredible Chemical Compatibility

FEP film is inert and provides incredible resistance for all kinds of chemicals, except alkali metals, gaseous fluorine, and some complex halogenated compounds. It also provides low permeability when dealing with different types of compounds.

Superior Electrical Efficiency

FEP retains electrical properties over large areas of film. With a dielectric strength of over 6,500 V/mil, the tubing solution ensures that there is no electrical tracking or wetting.

Excellent Thermal Range

FEP works efficiently at temperatures in the range of -240 degrees Celsius to 205 degrees Celsius. Moreover, it is also heat sealable.

Outstanding Mechanical Toughness

With incredibly low frictional properties, FEP provides anti-stick capabilities. It is also highly resistant to impact and tearing, which makes it one of the most suitable chemical manufacturing materials.

Strong Weatherability

FEP offers strength and is inert to outdoor exposure. Equipment manufactured from FEP tubing demonstrates no measurable changes even after 20 years. It also has amazing UV transmission ratings.

Some Applications

Generally, FEP tubing is used where superior chemical resistance is required or where working at extremely lower temperatures is desired. From manufacturing environmental monitoring equipment to producing medical equipment, FEP tubing can be used for a variety of purposes.
Since FEP is resistant to many industrial solvents, acids and bases, it has many applications. Some of them include:

  • FEP tubing can be used for sterile filling and dispensing systems.
  • It can be used to make diagnostic equipment.
  • It can be employed in cell and tissue culture technology.
  • It can be used to design and process equipment in fields, such as biotechnology and pharmaceutical.
