Chinese name: polytetrafluoroethylene
Chinese alias: PTFE; Teflon; Teflon; teflon; Teflon; 4F; king of plastics; Teflon is a kind of high-temperature and high-pressure resistance, corrosion-resistant electronic wire, the main material is polytetrafluoroethylene, so it is also called PTFE electronic wire.
Teflon is polymerized from tetrafluoroethylene polymer compounds, its structural formula is -[-CF2-CF2-]n-, with excellent chemical stability, corrosion resistance, is one of the world’s best corrosion-resistant materials, in addition to molten alkali metals, chlorine trifluoride, chlorine pentafluoride, and liquid fluorine, resistant to all other chemicals, is widely used in a variety of occasions requiring resistance to acids, alkalis and organic solvents. It has sealing, high lubrication and non-stickiness, electric insulation and good anti-aging ability, excellent temperature resistance (can work for a long time under the temperature from positive 250℃ to negative 180℃).

3. Teflon PTFE features
1、High temperature resistance with a working temperature of 250 ℃.
2, low-temperature resistance has good mechanical toughness; even if the temperature drops to -196 ℃, can maintain 5% elongation.
3, corrosion resistance to most chemicals and solvents, showing inertia, resistance to strong acids and alkalis, water and various organic solvents.
4, climate-resistant plastics have the best aging life.
5, high lubrication is the lowest coefficient of friction in solid materials.
6, non-adhesion is the smallest surface tension in solid materials, non-adhesion of any substance.
7, non-toxic with physiological inertia, as artificial blood vessels and organs long-term implantation without adverse reactions.
8、Electrical insulation can resist 1500 volts high voltage electricity.
9, atmospheric aging resistance: irradiation resistance and low permeability: long-term exposure to the atmosphere, the surface and performance remain unchanged.
10, non-combustibility: limit oxygen index below 90.
11, acid and alkali resistance: insoluble in strong acids, alkalis and organic solvents (including magic acid, that is, fluorine antimony sulfonic acid).
12、Oxidation resistance: it can resist the corrosion of strong oxidizing agents.
13、Weathering resistance
Teflon has very high chemical resistance, for example, in concentrated sulfuric acid, nitric acid, hydrochloric acid, and even boiling in aqua regia, its weight and performance are unchanged, and almost insoluble in most of the solvents, and only slightly soluble in all-alkanes above 300 ℃ (about 0.1g/100g). Polytetrafluoroethylene does not absorb moisture, non-combustible, oxygen, ultraviolet light are extremely stable, so it has excellent weather resistance.
14, electrical properties Teflon in a wide frequency range of dielectric constant and dielectric loss are very low, and breakdown voltage, volume resistivity and arc resistance are high.
15, radiation resistance PTFE radiation resistance is poor (104 rads), by high-energy radiation caused by degradation, the electrical properties of polymers and mechanical properties are significantly reduced.

Household appliances industry, can be used for air conditioners, microwave ovens, electronic sterilizers, rice cookers, electronic hot water bottles, electric heaters, electric ovens, electric frying pans, lamps and lanterns and other internal wiring.
5. What are the specifications of Teflon PTFE?
The specifications of Teflon very fine electronic wire are available in a variety of choices such as diameter (usually below 0.1mm), color (usually white) and length, and the specifications are 1331, 1332, 10064, 1371 and so on.
6. The difference between PVC and Teflon:
Insulation thickness is different, Teflon is thinner. Temperature and cold resistance is different, Teflon has good heat resistance. The rated temperature of Teflon wire can be in the middle of 105-250 degrees, while the rated temperature of PVC wire is generally in the middle of 60-105 degrees. Flame resistance is different, Teflon’s flame resistance is good, not easy to be ignited, while PVC wire can be ignited. Appearance is different, the two have different coloration, PVC material will look more dark yellow, while Teflon is brighter.
