Teflon is a common name, the scientific name is Teflon (abbreviated as Teflon or [PTFE, F4]), and is known as / "Plastic King", also known as "Teflon", "Teflon" (teflon), "Teflon", "Teflon", "Teflon" and so on. It is a polymer compound obtained by polymerizing tetrafluoroethylene, and its structure is simply -[-CF2-CF2-]n-.
High temperature resistance - use working temperature up to 250 °C. The long-term use temperature is 200~260 degrees.
Low temperature resistance - good mechanicalWhite 19mm PTFE Tape Factory toughness; 5% elongation even at temperatures down to -196 °C. It is still soft at -100 degrees.
Corrosion resistance - It is inert to most chemicals and solvents, resistant to strong acids and alkalis, water and various organic solvents. Resistant to aqua regia and all organic solvents.
Weather resistant - the best aging life in plastics.
Highly lubricated – the lowest coefficient of friction in solid materials. Has the smallest coefficient of friction (0.04) in plastic. It is smoother than ice.
Non-adhesive - is the smallest surface tension in solid materials and does not adhere to any substance.
Non-toxic - physiologically inert, long-term implantation of artificial blood vessels and organs without adverse reactions.
Ageing resistance - radiation resistance and low permeability: long-term exposure to the atmosphere, surface and performance remain unchanged.
Non-combustible - the oxygen limit is below 90.
Acid and alkali resistant - insoluble in strong acids, strong bases and organic solvents (including clarified acid, ie fluoroanthracene).
Antioxidant - resistant to corrosion by strong oxidants.
Insulation - excellent electrical properties, is an ideal Class C insulation material, a thick layer of newspaper can block the high voltage of 1500V. Its electrical insulation is not affected by temperature. The dielectric constant and dielectric loss are low in a wide frequency range, and the breakdown voltage, volume resistivity, and arc resistance are both high.
Acidity and alkalinity - neutral.
