Product Description

                                                                    FEP tube

Fluorinated ethylene-propylene tubing or FEP tubing is a nice alternative to PTFE teflon tubing and PFA tubing that exhibits many similar properties such as biocompatibility and a remarkable inertia to most chemicals. This flexible material with very good optical clarity, is mostly used for low-pressure microfluidics.

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.

HOT SIZES:  2x4,  4x6, 3x5,  5x6,  6x8, 5x8,  8x10, 10x12, 12x14.....(ID X OD,  Unit:mm)

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.



FEP Tubing offers excellent clarity which makes it ideal for sight glass/flow monitoring applications. FEP Tubing has a slightly higher coefficient of friction, lower continuous service temperature, and is more transparent then PTFE. FEP Tubing also has better gas and vapor permeability properties and excellent UV transmission ratings.

Key Properties:

• Cost-effective fluoropolymer and alternative to PTFE
• Excellent UV transmission, electrical, and better mechanical properties than PTFE
• Longer continuous tubing lengths available compared to PTFE
• Great for cabling, electrical insulation, water disinfection, environmental, and food contact applications
• Preferred material where tubing clarity or organization is desired
• Use temperature of 450 F (~230 C)
• Comes in blue, yellow, black, red, and clear

FEP Tubing Applications:
Aerospace &Transportation Technology, Electronics, Components & Insulators, Chemical & Pharmaceutical Manufacturing, Food Processing, Environmental Sciences, Air Sampling, Fluid Transfer Devices and Water Processing Systems
