1. The full name of FEP is Fluorinated ethylene propylene, which translates to fluorinated ethylene propylene copolymer (perfluoroethylene propylene copolymer) English trade name: Teflon* FEP, which 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 (grams/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 range of temperature and frequency.
FEP film 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.
The 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 water dispersion. Semi-finished products include tubes, membranes, plates, rods and single fibers.
Its main purpose is to make linings for pipes and chemical equipment, surface layers of drums, and various wires and cables, such as aircraft hook wires, booster cables, alarm cables, flat cables and oil well logging cables. FEP film has been used as a thin coating for solar collectors.

F-46 resin not only has similar characteristics to PTFE, but also has good processing properties of thermoplastics. Therefore, it makes up for the deficiencies of the difficult processing of PTFE, making it a material to replace PTFE, and is widely used in the production of wires and cables for electronic equipment transmission wires used under high temperature and high frequency, connecting wires inside electronic computers, Insulation layer of aerospace wires and special purpose installation wires, oil pump cables and winding wires of submersible motors.

The scientific name of Teflon rod is called polytetrafluoroethylene (English abbreviation is Teflon or [PTFE, F4]). "Teflon" (teflon), "Teflon", etc. It is a polymer compound formed by polymerization of tetrafluoroethylene, and its structure is simply -[-CF2-CF2-]n-.
The long-term use temperature of Teflon rod is 200~260 degrees. Low temperature-good mechanical toughness, even if the temperature drops to -196 degrees Celsius, it can maintain 5% elongation. It is still very soft at minus 100 degrees. Corrosion resistance-inert, strong acid, strong alkali, water and various organic solvents are most chemicals and solvents. It can withstand water and all organic solvents. Weathering-better aging life in plastics. High lubrication is the smallest coefficient of friction in solid materials. Its coefficient of friction is the smallest among plastics (0.04).
Acid and alkali resistance, insoluble in strong acids, strong alkalis and organic solvents (including magic acid, fluoroantimony sulfonic acid). Oxidation resistance-strong oxidant corrosion. Excellent insulation performance, it is an ideal C-level insulating material, a thick layer of newspaper can block the high voltage of 1500V. Its electrical insulation is not affected by temperature. The wide-band dielectric constant and dielectric loss are very low, and the breakdown voltage, volume resistivity and arc resistance are all high.
Teflon sticks are more stable than ice. Non-adhesion is the smallest surface tension in solid materials and does not adhere to any substance. No toxicity-physiological inertia, such as artificial blood vessels and organs implanted in the body for a long time, no adverse reactions. Aging resistance-radiation resistance and low penetration: exposed to the atmosphere for a long time, the surface and performance remain unchanged. Non-flammability-The oxygen restriction index is less than 90.
