What material is Teflon?
When we studied chemistry, we all learned polytetrafluoroethylene, molecular formula: C2F4, tetrafluoroethylene is mainly made from chloroform, and it can also be made by catalytic dechlorination of tetrafluorodichloroethane in the presence of chlorine trifluoride. It is a colorless and odorless gas at room temperature, with a boiling point of -76.3°C, which can be liquefied under pressure, with a critical temperature of 33.3°C and a critical pressure of 3.92MPa. Unlike many other fluorohydrocarbons, tetrachloroethylene is toxic and is mainly used to produce polytetrafluoroethylene with a wide temperature range and high chemical stability; it can also be copolymerized with ethylene or hexafluoropropylene to prepare fluorine-containing insulating materials, or with Vinylidene fluoride copolymerization produces fluorine-containing fibers.
Teflon is the common name of Teflon, so Teflon is processed from Teflon and other materials.
Teflon is commonly known as "Plastic King", and is also known as "Teflon", "Teflon", "Teflon", "Teflon" and so on.
Teflon tube product features
1. High chemical stability: can withstand all strong acids, including aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acids, etc., strong alkalis, strong oxidants, reducing agents and various organic solvents . It is very suitable for feeding high-purity chemicals.
2. Low friction coefficient: The friction coefficient is generally only 0.04, which is a very excellent self-lubricating material, and the friction coefficient does not change with temperature changes.
3. Excellent anti-sticking property, and the inner wall of the tube is not easy to adhere to colloids and chemicals.
4. Excellent aging resistance, can be used outdoors for a long time.
5. Excellent electrical insulation performance: PTFE is a highly non-polar material with good dielectric properties, great resistance, and a dielectric constant of about 2.0, which is the smallest among all electrical insulation materials.
6. Part of the tube has high transparency, and the internal fluid condition can be easily observed.
