PPSU is a slightly amber linear polymer. In addition to strong polar solvents, concentrated nitric acid and sulfuric acid, it is stable to general acids, alkalis, salts, alcohols, aliphatic hydrocarbons, etc. Partially soluble in ester ketones' aromatic hydrocarbons, soluble in halocarbons' DM. Good rigidity and toughness, temperature resistance, heat oxidation resistance, excellent creep resistance, corrosion resistance of inorganic acids, alkalis and salt solutions, ion radiation resistance, non-toxic, good insulation and self-extinguishing properties, easy to form and process.
1. PPSU is suitable for the production of heat-resistant parts, insulating parts, wear reduction parts, instrumentation parts and medical device parts, and polyaryl sulfone is suitable for making low-temperature working parts.
2. Polysulfone is commonly used in the electronic and electrical industry to manufacture integrated circuit boards, coil tube frames, contactors, sleeves, capacitive films, and high-performance alkaline battery shells.
3. Polysulfone is used in household appliances for microwave oven equipment, coffee heaters, humidifiers, hair dryers, cloth dryers, beverage and food dispensers, eating tableware, water cups, feeding bottles, etc. It can also replace non-ferrous metals for precision structural parts such as clocks, copiers, and cameras.
4. Polysulfone has passed the relevant specifications in the field of medicine and food in the United States, and can replace stainless steel products. Due to the characteristics of vapor resistance, hydrolysis resistance, non-toxicity, high temperature vapor disinfection, high transparency and good dimensional stability, polysulfone can be used as surgical tool plate, sprayer, fluid controller, heart valve, pacemaker, gas mask, tooth tray, etc.
