Characteristics and application of PPSU resin
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, and aliphatic hydrocarbons. Partly soluble in ester ketones and aromatic hydrocarbons, soluble in halocarbons and DM. Good rigidity and toughness, temperature resistance, heat oxidation resistance, excellent creep resistance, corrosion resistance of inorganic acids, alkalis, salt solutions, ion radiation resistance, non-toxic, good insulation and self-extinguishing, easy to mold and process.
1. PPSU is suitable for making heat-resistant parts, insulating parts, wear-reducing and wear-resistant parts, instrument parts and medical equipment parts, and polyarylsulfone is suitable for making low-temperature working parts.
2. Polysulfone is often used in the electronic and electrical industry to manufacture integrated circuit boards, coil bobbin holders, contactors, sleeve holders, capacitor films, and high-performance alkaline battery casings.
3. Polysulfone is used in household appliances for microwave oven equipment, coffee heaters, humidifiers, hair dryers, cloth steaming machines, beverage and food dispensers, eating utensils, water cups, milk bottles, etc. It can also replace non-ferrous metals for precision structural parts such as clocks, copiers, cameras, etc.
4. Polysulfone has passed the relevant regulations in the field of medicine and food in the United States, and can replace stainless steel products. As polysulfone is resistant to steam, hydrolysis, non-toxic, resistant to high-temperature steam sterilization, high transparency, and good dimensional stability, it can be used as a surgical tool tray, sprayer, fluid controller, heart valve, pacemaker, gas mask, Tooth tray and so on.
Because PPSU is a safe material, it does not contain carcinogenic chemicals (environmental hormone: bisphenol A) that disrupt endocrine, and as a heat-resistant material, the heat-resistant temperature is as high as 207 degrees. Due to repeated high temperature boiling, steam sterilization. It has excellent drug resistance and acid and alkali resistance, and can withstand cleaning with general syrups and detergents without chemical changes. Lightweight, drop-resistant, no matter in terms of safety, temperature resistance, hydrolysis resistance and impact resistance. But the price is relatively high
