FEP, also known as Fluorinated Ethylene Prolene, is a type of chemical substance. FEP is copolymerized by tetrafluoroethylene and Hexafluoropropylene. It is a modified material of polytetrafluoroethylene. This material does not ignite and can prevent the spread of flames. It has excellent wear resistance, low friction coefficient, and can be used from low temperature to 392F. This material can be made into granular products for extrusion and molding, used as powder for fluidized bed and electrostatic coating, and can also be made into aqueous dispersions. The semi-finished products have films and plates. Rods and single fibers.
Characteristics of FEP
1. It has both rigidity and flexibility, with sufficient mechanical properties and excellent flexibility.
2. The corrugated pipe per unit length is lighter, saves materials, reduces energy consumption, and is cheaper.
3. Strong chemical resistance, able to withstand the effects of acidity and alkalinity in the surrounding environment.
4. The corrugated shape can increase the resistance of the pipeline to the surrounding environment without increasing its flexibility, so it can be continuously laid on uneven objects.
5. Convenient interface, good sealing performance, convenient carrying, easy installation, reduced labor intensity, and shortened construction period.
6. Wide working temperature range, flame retardant, self extinguishing, and safe to use.
7. Excellent electrical insulation performance, making it an ideal material for wire sleeves.
8. Non ignition can prevent the spread of flames. It has excellent weather resistance, low friction coefficient, and can be used from low temperature to 392F.
Several Forming and Processing Methods of FEP
1. Melt extrusion molding
2. Molding: heating, pressure plasticizing; Cooling, pressurization and shaping
3. Blow molding
4. Vacuum forming
5. Injection molding
6. Coating processing
7. Electrostatic spraying
