First, the material introduction:
PPSU is an amorphous thermoplastic with high transparency and hydrolytic stability, and its products can withstand repeated steam disinfection. The scientific name of PPSU is polyphenylene sulfone tree. PPSU polyphenylene sulfone resin is a series of PSF products and a new type of thermoplastic engineering plastic. Refers to the polymer compound with sulfone group and aromatic nucleus on the molecular main chain, which is amorphous.
Polyphenylene sulfone resin is composed of basic resin prepared by the reaction of p-polyphenylene sulfide and peracetic acid. The p-polyphenylene sulfide used to prepare polyphenylene sulfone is prepared by the reaction of sodium sulfide and p-dichlorobenzene. The minimum weight average molecular weight of this kind of polyphenylene sulfone resin is 5000 daltons, and the added auxiliary materials are 170 to 189, which are allowed to be used in various parts, and are recognized as safe substances in food.
Second, the use:
It is suitable for making heat-resistant parts, insulating parts, wear-resistant parts, instrument parts and medical equipment parts, and polyarylsulfone is suitable for making low-temperature working parts.
Polysulfone is usually used to manufacture integrated circuit boards, coil formers, contactors, sheaths, capacitor films and high-performance alkaline battery casings in electronic and electrical industries.
Polysulfone is used in household appliances, such as microwave oven equipment, coffee heaters, humidifiers, hair dryers, dryers, beverage and food distributors, tableware, water cups, milk bottles and so on. It can also replace non-ferrous metals for precision structural parts such as watches, copiers and cameras.
Polysulfone has passed the relevant specifications in the fields of medicine and food in the United States, and can replace stainless steel products. Polysulfone can be used as surgical tool tray, sprayer, fluid controller, heart valve, pacemaker, gas mask, denture and so on. Because it has the characteristics of steam resistance, hydrolysis resistance, non-toxicity, high temperature steam disinfection resistance, high transparency and good dimensional stability.
PPSU is a reassuring material, which contains no chemicals that interfere with endocrine, and as a material with excellent heat resistance, the heat resistance temperature is as high as 207 degrees. Because it can be disinfected repeatedly with high-temperature boiling steam, it has excellent drug resistance and acid and alkali resistance, and can withstand the cleaning of general potions and detergents without chemical changes.
