FEP applications:

used for making insulation electronic parts, insulation layer for electric wires, chemical pumps, anti-corrosion liner of valves, anti stick sheath for drums of textile and light industries, etc.


Fluorinated ethylene-propylene resin,as a copolymer of tetrafluoroethylene and hexafluoropropylene, has good heat stability, outstanding chemical inertness, excellent electrical insulation and low friction coefficient, and can be processed by a thermoplastic processing method.

Mainly used for aviation, aerospace, subway vehicles, automatic switchgears, oil well testing equipment, fire alarming system, high-rise buildings, near fire zone wires, cables, computers, communication network and electricity, especially high-speed extrusion small-bore wire insulation materials. More economic for most purposes without needing high stress crack resistance.




Physical properties of FEP injection molding material

At present, the determination of molecular weight of F46 resin is still unsolved. However, its melt viscosity at 380℃ is lower than that of PTFE, i.e.103-104Pa.s, which shows that its molecular weight is much lower than PTFE.

The melting point of F46 differs with the components of its copolymer. When the content of Hexafluoropropylene in the copolymer increases, the melting point decreases. According to the DTA method, the melting point of domestic F46 lies between 250 and 270℃, lower than that of PTFE.


F46 resin is a kind of crystalline high polymer and its crystallinity is lower than that of PTFE. When melted F46 cools below the temperature of its crystalline melting point, the macromolecule will crystallize itself again, with a crystallinity of 50-60%. When the melted body cools by quenching, its crystallinity is lower, lying between 40% and 50%. The crystalline structure of F46 is spherocrystal structure and differs depending on processing temperature and thermal treatment method.

Electric Insulation Property of FEP Injection Molding Material

The electric insulation property of F46 is very similar to that of PTFE. The dielectric coefficient of F46 almost keeps constant from deep cooling to highest work temperature as well as in a large range of UHF from 50Hz to 1010Hz and is as low as around 2.1. The dielectric loss angle tangent of F46 changes with the frequency to some extent but changes little with temperature.

The volume resistance of F46 resin is very high, larger than 1015.m. It changes very little with temperature and is not affected by water and humidity. The arc resistance time of F46 is longer than 165s.

The breakdown of F46 increases with the reduction of its thickness. When its thickness is larger than 1mm, the breakdown field strength is above 30KV/mm, but do not change with temperature.

Thermal property of FEP injection molding material

The thermal stability of F46 resin is next to that of PTFE and can be continuously used in the temperature range of -85~+200℃. Even at the limiting temperatures of -200℃ and +260℃, its property still keeps stable and can be used in a short time.

The thermal decomposition temperature of F46 is higher than its melting temperature and will occur above 400℃. The decomposition products are TFE and HFP. As the equal end groups of the macromolecules of F46 will decompose above its melting point, please give proper ventilation when processing it at temperature of above 300℃. F46 is stable under its melting point but the loss of its mechanical strength at 200℃ is comparatively great. The reduction of melt viscosity and thermal decomposition of copolymer can be analyzed by melt index.

F46 will not become hard and brittle at -250℃ and still keeps a very tiny elongation and certain flexibility, even better than that of PTFE. As a result, it is far better than any other plastics.
