Properties of 1. FEP polytetrafluoroethylene
FEP is an important TFE copolymer. Its performance is 50 degrees Celsius lower than PTFE at the highest operating temperature, and other properties are equivalent to PTFE. It is widely used in electronic, electrical, chemical and other industries.
industry, especially in the high-performance, high quality wire and cable preparation, communications, aerospace, precision instruments and other fields.
(1) Thermal performance: FEP has good thermal performance and can withstand high and low temperatures.
(2) Electrical properties: FEP is an excellent electrical insulation material at low temperatures to 200 degrees Celsius. Even after soaking in water for a long time, its volume resistivity does not change.
(3) Chemical properties: FEP's chemical resistance is similar to that of PTFE, and it can resist corrosion of strong acid, strong alkali, aqua regia and various organic solvents.
(4) Mechanical properties: mainly include tensile strength, elongation, yield strength, impact strength, hardness, etc.
(5) Other properties: FEP has similar hydrophobicity and non-adhesion to PTFE.

Molding and processing method of 2. FEP polytetrafluoroethylene
The product forms before FEP resin processing and molding are:
1. Pellet, used for extrusion molding and injection molding;
2, dispersion, used for impregnation and coating;
3. Powder for electrostatic spraying.
Below we mainly understand the FEP under several molding processing methods.
1, Melt extrusion molding
2. Molding: heating, pressurizing and plasticizing; cooling, pressurizing and shaping
3. Blow molding
4. Vacuum forming
5. Injection molding
6. Coating processing
7. Electrostatic spraying

Use of 3. FEP polyethylene glycol
FEP is an earlier commercially available copolymer for TFE after PTFE and is a melt-processable perfluorinated plastic.
FEP resin has almost all the excellent properties of PTFE resin, its unique advantage is that it can be melt processed, through injection molding and extrusion molding, improve performance and application range, mainly widely used in
under the field.

(1) Electronics and electrical industry: the production of wires, cable coatings, according to plug-ins, high-frequency electronic equipment transport lines, electronic computer wire insulation and parts;
(2) chemical industry: the production of pipes, valves, pumps, containers, tower anti-corrosion lining, heat exchangers and anti-corrosion filter;
(3) Machinery industry: making seals and bearings;
(4) Defense industry: production of aviation wires, special coatings and spare parts;
(5) medicine: repair heart valves and small trachea, etc.
In recent years, China's high-rise buildings due to electrical insulation caused by the fire has occurred, if the use of electrical insulation performance of outstanding FEP materials, you can minimize the hazards of these fires.
