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.
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 50 degrees F lower.
Unlike other fluoropolymer tubing, long continuous lengths of FEP tubing can also be produced by extrusion. The relatively low cost and desired properties of 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.
