The Basic Information of Telfon FEP Resin and FEP Powder
- Jun 15, 2018 -

FEP name: Hexafluoro propene-tetrafluoroethylene copolymer  that is FEP, Fluoropolymer

CAS Number : 25067-11-2

Package: plastic bag, Each package of 25KG

FEP raw material products Usage: for the manufacture of electronic insulation parts, wire insulation layer, chemical pumps, valves corrosion resistance lining, The copolymers of perfluoroethylene propylene copolymer (FEP), also known as fluoroplastics, are made of transparent particles (suspension polymers) or water dispersions (emulsion polymerizers).

The properties of the copolymers of perfluoroethylene propylene copolymers and PTEE are similar to those of PTEE. However, the heat resistance is slightly lower and can be worked for a long time at -85 degrees 205 degrees and short-term from -200 degrees to 300 degrees; high impact strength, creep resistance and low temperature flexibility are better than PTEE; crystallinity varies with the heat treatment temperature and is good in formability; non-toxic, non-sticky, Electrical insulation, wear resistance, chemical stability are comparable to PTEE; coloring, waste can be recycled. Polyfluoroethylene propylene copolymer-FEP molding process can be molded, transfer molding, injection molding, extrusion, thermal molding, machining, spraying, dispersible impregnation, coating, brush, hot seal, adhesive. Use of polyfluoroethylene propylene copolymer-FEP: same as PTEE, the finished product has plates, rods, tubes, laminated materials, wire and cable, can be mixed with glass powder SIO2, copper powder and other fillers, dispersive coating is mainly used for anticorrosion, Impermeability (because its permeability is superior to PTEE, resistance to seawater and salt dew.

Our FEP Resin features: FEP resin has excellent resistance to high temperature, low temperature, It can be used at -80 ℃ ~ 250 ℃ for a long time: weather aging resistance, fire resistance, high oxygen index, no water absorption, excellent radiation resistance, such as long-term exposure to the atmosphere, its surface and properties remain basically unchanged, excellent dielectric properties, high pressure resistance; Excellent corrosion resistance, almost insoluble in any solution, no corrosion in strong acid Wang Shui, strong alkali concentrated sodium hydroxide, strong corrosion agent uranium pentafluoride; good corrosion resistance, static friction coefficient is the smallest in plastics, excellent self-lubricating performance, Has prominent surface non-viscosity; good tensile strength. Widely used in aerospace, instruments, electronic appliances, post and telecommunications, petrochemical, metallurgical power, machinery and equipment home appliances, Lighting.

FEP Application:

1 FEP suitable for making corrosion resistant parts, wear resistant parts, seals, insulation and medical equipment parts;

2 FEP can make high-temperature wire, cable insulation, anticorrosion equipment, sealing materials, pump valve bushing and chemical containers. Molding properties: crystallization, moisture absorption can be processed by the usual thermoplastic processing method.

3 FEP fluidity is poor, easy to decompose, decomposition of corrosion gas. The molding temperature should be strictly controlled not to exceed 475 degrees, the mold should be heated to 150-200 degrees, and the casting system should have a small resistance to the flow of materials.

4 FEP translucent particles, injection molding, extrusion molding, Long-term temperature tolerance 260 degrees molding temperature 350-400 degrees or 475 degrees above easy to cause color change or bubble.

5 Due to the corrosive effect of FEP melting materials on metal, the chemical properties of mould need electroplating chromium treatment. PFA is similar to FEP PTFE, but FEP can only use PTFE less than 200 degrees can not be injected.
