PSU application
PSU has a wide range of applications. In the field of electronics and electricity, PSU can be used to make various electrical parts such as contactors, connectors, transformer insulators, thyristor caps, insulating sleeves, coil bobbins, terminals and slip rings, and printing Circuit boards, bushings, covers, TV system parts, capacitor films, brush holders[1], alkaline battery boxes, etc.; in the automotive and aerospace fields, PSU can be used to make protective cover components, electric gears, battery covers, detonators, Electronic ignition device components, lighting components, aircraft interior parts and aircraft exterior parts, outer protective covers of aerospace vehicles, etc. It can also be used for PSU to make luminaire baffles, electric transmissions, sensors, etc. The demand for polysulfone polymers used to make cabin parts in the world market continues to grow.
Mainly because this kind of polymer releases less heat and produces less smoke when burned, and less toxic gas diffusion, which fully meets the use requirements of safety regulations; in the kitchen supplies market, PSU can replace glass and stainless steel products for making steam Dinner plates, coffee containers, microwave cookers, milk and agricultural products containers, egg cookers and milker parts, beverage and food dispensers and other products. PSU is a non-toxic product that can be made into utensils that come into contact with food repeatedly. As a new transparent material, PSU has better heat-resistant water and hydrolytic stability than any other thermoplastic, so it can be used to make coffee pots. The connecting pipe made of PSU is used for glass fiber or glass fiber reinforced polyester wall cladding. The outer layer of the pipe has high strength and the inner layer of the pipe is chemical resistant. It is lighter than steel pipes and is transparent. It is convenient for temporary control. It is often used in the food industry and production. Lamps with strong lights; in terms of sanitation and medical equipment, PSU can be used to make surgical trays, sprayers, humidifiers, contact lens fixtures, flow controllers, instrument covers, dental equipment, liquid containers, pacemakers, respirators, and Laboratory equipment, etc. PSU is used to make various medical products at a lower cost than glass products, and it is not easy to break, so it can be used in instrument housings, dental instruments, heart valve boxes, blade cleaning systems, soft contact lens forming boxes, micro filters, dialysis membranes, etc. . PSU can also be used for dental implants, and its bonding strength is twice that of acrylic; in terms of daily necessities.
PSU can be used to make heat-resistant and hydrolysis-resistant products such as humidifiers, hair dryers, clothing steaming, camera boxes, and projector components. After 0.4-1.6MGy radiation and well-dried PSU pellets, it can be easily injection molded at 310°C and a mold temperature of 170°C. It is suitable for adhesives for laminates. All polysulfones with silane such as PSU-SR, PKXR, etc. can be used as adhesives for sizing glass fiber and graphite fiber to make composite materials. PSU with silyl groups reinforced with graphite fabric can be used to make elevators and other aircraft parts. After adding solid lubricant polytetrafluoroethylene, PSU can increase wear resistance and physical and mechanical properties, and can also be used to prepare wear resistant coatings. In addition, PSU can also manufacture various chemical processing equipment (such as pump housings). , Tower outer protective layer, etc.), food processing equipment, pollution control equipment, dairy product processing equipment and engineering, construction, chemical pipelines, etc.
