PSU has a wide range of applications, in the field of electrical and electronic, PSU can be used to make a variety of contactors, connectors, transformer insulation, SCR caps, insulating bushings, coil bobbins, terminal blocks and collector rings and other electrical parts, printed circuit boards, bushings, hoods, TV system parts, capacitor film, brush holders, alkaline battery boxes, etc.; in the field of automotive, aviation, PSU can be used to Production shield components, electric gear, battery cover, detonators, electronic firing device components, lamps and lanterns parts, aircraft internal accessories and aircraft external parts, spacecraft external shield and so on. PSU can also be used to produce illuminator gear, electric drives, sensors, etc., the world market used to make cabin parts of polysulfone polymer demand continues to grow, mainly due to the combustion of such polymers release less heat, produce less smoke, less diffusion of toxic gases, in full compliance with the safety regulations of the use of the requirements; in the kitchenware market, PSU can be used in place of glass and stainless steel products for the Manufacture of steam trays, coffee containers, microwave cookers, milk and agricultural products containers, egg stoves and milking parts, beverage and food dispensers, etc. PSU is a non-toxic products can be made into repeated contact with food utensils. PSU as a transparent new material, heat and water resistance, hydrolytic stability is better than any other kind of thermoplastic, so it can be used to make coffee pots and so on. Connection tube made of PSU, used for glass fiber or glass fiber reinforced polyester masonry, tube outer layer of high strength, tube inner layer of chemical resistance, lighter than steel, and transparent, easy to clinical control, commonly used in the food industry and the production of lamps and lamps of the lamps; in the health and medical equipment, PSU can be used for the production of surgical trays, nebulizers, humidifiers, contact lens fixtures, flow rate controllers, instrument covers, dental instruments, liquids, and medical devices. PSU can be used to make a variety of medical products than the cost of glass products, and not easy to rupture, so it can be used for instrument housings, dental instruments, heart valve box, blade cleaning system, soft contact lens molding box, micro-filter, dialysis membrane, etc. PSU can also be used for dental veneers, the adhesive strength of which is twice as high as that of acrylic acid; in daily necessities, PSU can be used to make humidifiers, hair dryers, hair dryers and other products. In daily necessities, PSU can be used to make humidifier, hair dryer, clothing steam, camera box, projector components and other heat-resistant, hydrolysis-resistant products. By 0.4-1.6MGy radiation and good drying over the PSU granules, at 310 ℃ and mold temperature 170 ℃ is easy to injection molding, suitable for laminating materials, adhesives, all the polysulfone with silane, such as PSU-SR, PKXR, etc. can be used as an adhesive for the sizing of glass fibers and graphite fibers to make composite materials, graphite fabrics reinforced with silanes with the PSU, can be made to elevate the rudder and other aircraft parts. PSU in addition to the solid lubricant PTFE, can increase wear resistance and physical and mechanical properties, but also used in the preparation of wear-resistant coatings; in addition, PSU can also be manufactured in a variety of chemical processing equipment (such as the pump housing, tower outside the protective layer, etc.), food processing equipment, pollution control equipment, dairy processing equipment, and engineering, construction, chemical piping and so on.
