Polysulfone (PSF) has excellent physical and mechanical properties, high temperature creep resistance, hydrolysis resistance, non-toxicity, good electrical insulation and UV resistance, and its light weight and low cost can replace various plastics. It can also be used in place of metal, and can be processed by general methods such as injection, extrusion, and molding. It has been widely used in electronics, machinery, instrumentation, medical equipment, aviation, automotive, etc., and has maintained a steady growth momentum. Electronic and electrical field Electronic and electrical is currently a major consumer of PSF, and the development of electronic and electrical to small, lightweight, high temperature, and promote the growth of PSF consumption. PSF can be used to make electrical parts such as contactors, contacts, transformer insulation, thyristor caps, bushings, coil bobbins, binding posts and electrical rings, printed circuit boards, bushings, covers, video system parts, Capacitor film, brush holder, alkaline battery case, etc. Automotive, aviation In aerospace and automotive manufacturing, PSF is suitable for the manufacture of protective cover components, electric gears, battery covers, detonators, electronic ignition components, luminaire components, aircraft interiors and aircraft exterior parts, and external shields for astronauts. In addition, the PSF can also make illuminator baffles, electric drives, and sensors. Worldwide, the demand for polysulfone polymers used to make cabin components is growing, mainly because such polymers emit less heat when burned, produce less smoke, and have less toxic gas diffusion, which is fully safe. Requirements. Cookware, food processing machinery PSF is a non-toxic product confirmed by FDA in the United States and can be made into utensils that are repeatedly in contact with food. As a new transparent material, PSF is superior to other thermoplastics in heat-resistant water and hydrolytic stability. It can replace glass and stainless steel products and meet the required performance standards. In the kitchen market, PSF products include steam trays, coffee containers, microwave cookers, milk and produce containers, egg cookers and milker parts, beverages and food dispensers. In terms of food packaging, PSF can be used in a variety of containerware, using its microwave-permeable characteristics to make microwave vessels. In addition, PSF can also be used as a connecting pipe. The outer layer of the pipe has high strength, the inner layer is resistant to chemicals, lighter and more transparent than the steel pipe, and is convenient for control. It is often used in the food industry and in the manufacture of lampshades for glare lamps. The PSF in the sanitary and medical fields fully meets the hygiene requirements, and can withstand repeated disinfection of steam at 130 ° C. It can be used for sanitary medical devices instead of stainless steel and aluminum to reduce costs. Medical devices that can be made with PSF are: surgical discs, nebulizers, humidifiers, contact lens holders, flow controllers, instrument covers, dental instruments, pacemakers, respirators, and the like. Medical products made with PSF are less expensive than glass products and are not easily broken. Therefore, they are used for instrument housings, dental instruments, heart valve boxes, blade cleaning systems, molded boxes for soft contact lenses, micro filters, dialysis membranes, and the like. It can also be used for inserts, which are twice as strong as polyacrylates. Daily necessities application field The daily necessities made with PSF are mainly heat-resistant and hydrolysis-resistant products, including humidifiers, steam irons, camera boxes, and projector components. Adhesive, coating All silane-containing polysulfones can be used as a binder. Used for sizing glass fiber and graphite fiber to make composite materials. Aircraft parts such as elevators can be made with silane-based PSF reinforced with graphite fabric. PSF and solid lubricant polytetrafluoroethylene can be used together to make abrasion resistant coatings. Industrial applications PSF can also manufacture a variety of chemical processing equipment, including pump cover, tower protection layer, food processing equipment, pollution control equipment, dairy processing equipment and engineering, construction, chemical pipelines. The annual growth rate of the US PSF is 8% to 10%, the annual demand growth rate of PSF in Western Europe is 14% to 17%, and the annual growth rate of Japan's PSF is 7% to 8% PSF. Polysulfone is in short supply on the international market, and the United States, Western Europe, and Japan all need to be imported. In China, the application and development in the fields of food, health and medical care are still in the initial stage. From the perspective of development trend, the demand for PSF will continue to grow steadily.
