    1. Coating profiles
    Polytetrafluoroethylene, English full name for Polytetrafluoroetylene, referred to as Teflon, PTFE, F4 and so on. Polytetrafluoroethylene (Polytetrafluoroethene), commonly known as "non stick coating" or "easy to clean wok materials"; is a fluorine substituted all hydrogen atoms in polyethylene synthetic polymer materials. The material has the properties of acid fast, alkali resistance and various organic solvents. It is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, the friction coefficient is very low, so it can be used as lubricant remaining, also became the ideal coating and the inner pipe easy to clean wok.
    2.Coating features:
    2.1.Non adhesive: almost all substances are not bonded with PTFE coating. The thin films also show good adhesion properties.
    2.2.Heat resistance: PTFE coating has excellent heat resistance and low temperature resistance. Short time high temperature to 300 degrees Celsius, generally between 240 DEG ~260 DEG can be used continuously, has outstanding heat stability, it can work in freezing temperatures without brittle, does not melt at high temperature.
    2.3. Sliding: PTFE coating has a lower coefficient of friction. When the load is sliding, the coefficient of friction changes, but the value is only between 0.05-0.15.
    2.4. Moisture resistance: PTFE film surface water repellent and oil production, the operation is not easy to stick with a small amount of solution, such as sticky dirt, simply wipe clean. Short downtime, saving working hours and improving work efficiency.
    2.5. Wear resistance: under high load, it has excellent wear resistance. Under certain load, it has the dual advantages of abrasion resistance and non adhesion.
    2.6. Corrosion resistance: PTFE is almost not affected by the drug to withstand erosion, in addition to molten alkali metal fluoride medium and all acid is higher than 300 degrees Celsius outside of sodium hydroxide (including aqua regia), strong oxidant, reductant and various organic solvents, can protect the parts from corrosion of any kind.
    3. Chemical properties:
    3.1.Insulation: without environmental and frequency effects, volume resistance up to 1018 ohm cm, dielectric loss is small, breakdown voltage is high.
    3.2.High and low temperature resistance: the influence on temperature is little changed, temperature range is wide, and the temperature can be -190~260 degrees centigrade.
    3.3.Self lubrication: with the lowest friction coefficient in plastics, it is an ideal oil-free lubricating material.
    3.4. Surface is not sticky: known solid material can not adhere to the surface, is a surface energy of the smallest solid material.
    3.5. Is resistant to atmospheric aging, radiation resistance and low permeability: the long-term exposure to the atmosphere, surface and performance remain unchanged.
    3.6. Non combustibility: the oxygen limited index is below 90.
    3.7. PTFE is widely used in high temperature resistant and high viscosity industries. Among them, the strongest super acid - antimony acid can also be used to preserve it.
    4. Application areas:
    4.1. Can use PTFE pushing or extrusion molding; used in high temperature wire, can also be made into films and shaft PTFE bag, for the production of high frequency cable directly into the water solution, can be used for coating, dipping or fibers.
    4.2. PTFE in atomic energy, defense, aerospace, electronics, electrical, chemical, machinery, instruments, meters, construction, textile, metal surface treatment, pharmaceutical, medical, food, metallurgical smelting industry are widely used as high and low temperature resistance, corrosion resistant materials, insulation materials, anti sticking coating, which can not be replace the product.
