FEP Tubing

Get to Know Techyours™ FEP Tubing

The cost-effective brother of PTFE, FEP was developed as a conventionally melt-processible fluoropolymer in response to the limitations and initial difficulties in processing PTFE.

Techyours™ FEP tubing is a copolymer of TFE, the basic fluoro-monomer building block. The addition of a modifier results in a small, but meaningful departure from the properties of PTFE tubing. Mainly, it possesses a working pressure that is 30% higher, transparent walls, a small increase in stiffness, and a use temperature that is 60 degrees C lower.

Unlike other fluoropolymer tubing, long continuous lengths of Techyours™ FEP tubing can also be produced by extrusion. The relatively low cost and desired properties of Techyours™ FEP tubing drives its use in many applications that require high electrical breakdown voltage, low dielectric constant, high chemical resistance, high UV transmission, excellent sterilizability and longevity of use.

Techyours™ FEP Tubing In the World

Materials Overview

FEP

The development of PTFE (polytetrafluoroethylene) was a significant breakthrough in polymer science. The special processing requirements of PTFE led researchers to develop a melt–processable version of PTFE resulting in FEP. This new resin was compatible with existing processing methods and equipment. Melt processability also allowed for long continuous extrusions of FEP in applications such as wire and cable wrapping.

While similar to PTFE in many of its properties, FEP has its own preferred attributes. It has a slightly higher coefficient of friction, lower continuous service temperature, and is more transparent than PTFE. FEP also offers lower gas and vapor permeability properties and excellent UV resistance. FEP’s expanded attributes make it ideal for a diverse range of applications from environmental monitoring equipment to medical devices.
