In addition to strong polar solvents, concentrated nitric acid and sulfuric acid, it is stable to general acids, bases, salts, alcohols and aliphatic hydrocarbons. Partially soluble in ester ketone aromatic hydrocarbon, soluble in halogenated hydrocarbon DM. Good rigidity and toughness, temperature resistance, thermal oxidation resistance, excellent creep resistance, corrosion resistance of inorganic acid, alkali and salt solution, ion radiation resistance, non-toxicity, good insulation self-extinguishing, and easy molding and processing.
In a word, this kind of plastic has high transparency and hydrolytic stability, and its products can withstand repeated steam disinfection, so it is a new type of thermoplastic engineering plastic.
The widespread use of "PPSU":
(1) is suitable for making heat-resistant parts, insulation parts, wear-resistant parts, instrument parts and medical equipment parts, and polyarylene sulfone is suitable for making low-temperature working parts.
(2) Polysulfone is often used to manufacture integrated circuit boards, coil formers, contactors, sheaths, capacitor films, high-performance alkaline battery casings, etc. in the electronic and electrical industries.
(3) Polysulfone is used in household appliances, such as microwave oven equipment, coffee heaters, humidifiers, hair dryers, dryers, beverage and food distributors, tableware, cups, milk bottles, etc. It can also replace non-ferrous metals for precision structural parts such as watches, copiers and cameras.
