PPSU is an amorphous thermoplastic with high transparency and high hydrolytic stability. The products can withstand repeated steam sterilization.
PPSU, scientific name: polyphenylene sulfone resin (Polyphenylene sulfone resin) PPSU polyphenylene sulfone resin is a product of the Polysulfone (Polysulfone) abbreviated PSF series. Is a novel thermoplastic engineering plastics, refers to the main chain of molecules in the sulfone group and aromatic nuclei containing polymer compounds, non-crystalline.
Because PPSU is inherently non-toxic and does not release BPA, it is very friendly to infants and children as a food contact material. In the field of food containers, PPSU can be used to replace glass, metal ceramics and thermoset materials. Compared with other types of resins, PPSU tableware has excellent performance.
Applications:
1, medical equipment devices
PPSU materials can be placed in a steam sterilization environment almost infinitely, repeated sterilization sterilization, is widely used as a medical component sterilization, is used as a medical equipment devices stunt material, among them. There are surgical trays, nebulizers, heart method dirty valve, pacemaker, gas masks, dental trays, thermostats, dental instruments and other applications in the medical field.
2, electronic and electrical components
PPSU material also has excellent electrical insulation, and its material allows welding materials, as the production of electronic assembly applications, suitable for the production of circuit boards, coil tube frame, contactors, sets of shelves, capacitor film, alkaline battery shell, to do the shielding elements, electric gears, battery cover and so on. Electrical components.
3, household appliances accessories
PPSU material also has high temperature and high pressure, and food-grade plastics, heating does not produce toxic gases, often used in the manufacture of microwave oven equipment, coffee heater, wetter, hair dryer, cloth Yan open, beverage and food dispensers, dietary cutlery, cups, bottles and so on. It can also be used instead of non-ferrous metals in clocks and watches, photocopiers, cameras and so on.
4, industrial machinery parts
PPSU material also has a better than PSU and PEI impact resistance and chemical stability, can be used to make flow controllers and laboratory instruments, used for veneers with high bonding strength of adhesive bonding agent, such as chemical equipment in the pump enclosure, the tower of the outer protective layer, acid-resistant nozzles, pipes, valves containers and so on.
