The FEP tube is a modified Teflon tube with improved color transparency, 200°C temperature resistance, and airtightness. Fluorinated ethylene propylene is abbreviated as FEP, and the full name is polyperfluoroethylene propylene. FEP is a soluble fluoroplastic that is based on PTFE in order to improve its insoluble properties and difficult processing. FEP has nearly identical properties to PTFE in terms of corrosion and wear resistance, but its temperature resistance is limited to 200 degrees Celsius. FEP material is simple to work with and weld.

1. FEP, F46 (fluorinated ethylene propylene copolymer) non-stick coatings melt and flow during baking to form a non-porous film, with excellent chemical stability and non-stick properties, maximum use temperature of 200 °C, melting point of 270 °C, injection molding, extrusion molding

2. The non-stick coating PTFE (polytetrafluoroethylene) can be used continuously at 260°C, with a maximum operating temperature of 290-320°C, and has an extremely low friction coefficient, good wear resistance, and excellent chemical stability. It can’t be injected, but it can be extruded or coated.

As a result, PTFE is far more practical than FEP. The reason is simple: PTFE has better temperature resistance, anti-corrosion performance, and anti-stick performance than FEP due to its properties. However, due to cost considerations, FEP material is a good choice if the requirements aren’t too stringent and only require friction resistance.

What is FEP tubing, and how does it work?
FEP (Fluorinated Ethylene Propylene) is a semi-clear tubing that retains its strength and benefits over a wide temperature and environmental range. FEP tubing has superior chemical resistance, advanced gas and vapor permeability properties, and high UV transmission ratings.

The full name of FEP is Fluorinated ethylene propylene, which is translated into fluorinated ethylene propylene copolymer (perfluoroethylene propylene copolymer). English trade name: Teflon* FEP is a class of chemical substances. FEP is a copolymer of tetrafluoroethylene and hexafluoropropylene. The melting point of FEP crystal is 304°C, and the density is 2.15g/CC (gram/cubic centimeter).

FEP can be applied to soft plastics, and its tensile strength, wear resistance, and creep resistance are lower than many engineering plastics. It is chemically inert and has a low dielectric constant over a wide temperature and frequency range

FEP (fluorinated ethylene propylene) heat shrink tubing is chosen particularly for its lower shrink temperature than other heat shrinks such as PTFE. FEP also has greater flexibility, optical clarity, and high lubricity in comparison to PFA.

FEP Heat shrink Performance, parameters: Volume resistance>1018ΩM, surface resistance>1013Ω, arc resistance>165 seconds, no leakage, low friction coefficient of kinetic friction, 0.2-0.3, non-stick, water, oil-water contact angle θ=114о, non-flammable air will not burn (oxygen index >95VOL%), the shrink ratio is 1.7:1

Application Teflon FEP heat-shrinkable tube has outstanding wear resistance, chemical corrosion resistance and high temperature performance, especially suitable for high temperature performance occasions, used for insulation protection and pressure relief at connection welds and identification of coated components
