Why Are Wires Coated with FEP Tubing?

FEP is the abbreviation for Fluorinated ethylene propylene. It is a kind of fluoroplastic that is used as a cable outer to protect and insulate thermal sensor wire. It has very alike properties to PTFE and PFA such as little friction and non-reactivity to chemical substances. FEP or fluorinated ethylene propylene is a rough, supple copolymer of tetrafluoroethylene and hexafluoropropylene. It is frequently used for easy tubing and fluid processing equipment when chemical confrontation, high transparency, and less rigorousness are required. FEP has outstanding electrical assets and UV resistance capacity.

From the standpoint of the domain of chemical engineering and material science, the invention of FEP tubing was an implausible hop forward. It was the necessity of a more processable substance that encouraged engineers to look for more options and lastly led to FEP’s unearthing. Technically denoting, FEP wire is a copolymer of hexafluoropropylene and tetrafluoroethylene, with maximum features of PTFE (Polytetrafluoroethylene). FEP is more elastic-like and provides less heat shrink temperature range than PTFE. It is manufactured by conventional processing techniques, for example, inoculation moulding, film casting, and large-scale extrusion. Since FEP is resilient to many engineering solvents, acids, and bases, it has diverse applications. The important ones are for sterile filling and dispensing systems. FEB tubing can be used to manufacture medical investigative equipment. It can be active in cell and tissue culture technology. Moreover, it can be used to outline and process biotechnology and pharmaceutical apparatus in fields.

Benefits of FEP Tubing Coat on Wires and Pipes

FEP film is a see-through thermoplastic layer that can be heat wrapped, heat stuck, thermoformed, welded, and plastic-coated with other elements.

All of the above production properties linked with the succeeding features and benefits make it an idyllic choice for coating on wires.

Incredible Chemical Compatibility

FEP film is inactive and offers unbelievable resistance for all kinds of chemical substances, barring alkali metals, vaporous fluorine, and some complex halogenated compounds. It also has low penetrability when reacting with various types of compounds.

Superior Electrical Efficiency

FEP wire holds electrical properties over large parts of the film. With a dielectric forte of over 6,500 V/mil, the tubing solution safeguards that there is no electrical chasing or dampening.

Excellent Thermal Range

FEP works competently at temperatures in the series of -240 degrees Celsius to 205 degrees Celsius. Additionally, it is also thermally sealable.

Excellent Mechanical Hardiness

With extremely low frictional features, FEP offers anti-stick competences. It is also exceedingly resilient to effect and slitting, which makes it one of the most apposite chemical engineering ingredients.

Robust Weatherability

FEP cable offers the powerful capability and is inactive to open-air exposure. Wires coated with FEP tubing reveals no quantifiable changes even after 20 years. It also has remarkable UV transmission ratings.

Generally, FEP tubing is used where bigger chemical resistance is compulsory or where working at tremendously lower temperatures is looked-for. From coating the wires, manufacturing ecological monitoring apparatus to manufacturing medical equipment, FEP tubing can be used for variability of purposes. FEP cable is highly used in wire and cable insulation, minor tubing, and injection moulded parts. They are also used for moulded items for the chemical industry, jackets for wire and cable applications demanding a high degree of pressure crack confrontation. They are also used in industrial layering and filming, telecommunication cable jacketing, and fabric and film coating.

Exotherm Instruments is India’s leading PTFE wire manufacturing company. They specialise in the production of FEP insulated wires, PFA insulated wires, ETFE insulated wires, and Thermocouple wires.
