Polytetrafluoroethylene (abbreviated as Teflon or [PTFE, F4]) is widely used in the world as "Plastic King", Chinese brand name "Teflon", "Teflon", "Teflon" , "Teflon", "Teflon" and so on. It is made by the polymerization of tetrafluoroethylene polymer compounds, the structure of the formula is - [- CF2-CF2-] n-.
High temperature - working temperature up to 250 ℃. Long-term use of temperature 200 ~ 260 degrees.
Low temperature resistance - Good mechanical toughness; 5% elongation even at temperatures down to -196 ° C. It is still soft at -100 degrees.
Corrosion resistance - is inert to most chemicals and solvents, resistant to acids and bases, water and various organic solvents. Able to aqua regia and all organic solvents.
Weather resistant - the best aging life in plastics.
High lubricity - is the lowest friction coefficient in solid materials. Has the smallest coefficient of friction in plastic (0.04). More smooth than ice.
Non-stick - is the smallest surface tension in a solid material and does not adhere to anything.
Non-toxic - with physiological inertia, as long-term artificial blood vessels and organs implanted in the body without adverse reactions.
Anti-aging - Irradiation resistance and low permeability: long-term exposure to the atmosphere, the surface and properties remain unchanged.
Non-flammable - oxygen limit index below 90.
Acid and alkali - insoluble in strong acids, bases and organic solvents (including magic acid, that is, fluorine antimony sulfonic acid).
Anti-oxidation - can withstand strong oxidizer corrosion.
Insulation - Excellent electrical performance, ideal for Class C insulation, a newspaper thick layer can block 1500V high voltage. Its electrical insulation is not affected by temperature. Dielectric constant and dielectric loss over a wide frequency range are low, and the breakdown voltage, volume resistivity and arc resistance are high.
Acid-base - neutral.
