Polytetrafluoroethylene commonly known as"The Plastic King", a polymer made by polymerization of tetrafluoroethylene as a monomer. White, waxy, translucent, heat resistance, good cold resistance, long-term use -180~260 ℃. This material has the characteristics of acid and alkali resistance, resistance to various organic solvents, and is almost insoluble in all solvents. Following the recovery of fluorine plastic small series to understand and see its nature and stability.
1. Stable under normal temperature and pressure to avoid humidity, heat and high temperature without real melting point. Problems above 450 ℃ slowly begin to decompose and directly affect the change into a gas. At 27°C, the mechanical design strength suddenly disappears. Insoluble in any of these solvents. In addition to their own can react with molten alkali metal, not by any other social material erosion, even in aqua regia or fuming sulfuric acid, sodium hydroxide boiling, also can not afford any development and change.
2. White, odorless, tasteless, non-toxic powder, commonly known as "plastic king". It has excellent chemical stability, corrosion resistance, sealing, high viscosity lubrication, electrical insulation and good anti-aging endurance. Temperature resistance, the working temperature of 250 ℃. Low temperature resistance, low temperature toughness has good machinery, even if the temperature drops to -196 ℃, it can maintain 5% elongation. Resistant to most chemicals and solvents exhibits inertness, resistance to acids, alkalis, water and various organic solvents. Good weather resistance, anti-aging life plastic. High lubricity, the solid material is low coefficient of friction.
To sum up, this is the recycling of fluoroplastics.The Plastic KingThe nature and stability of the introduction, I hope can help you.
