1, PSU plastic material (Polysulfone Plastics) is the main chain of molecules containing sulfone and aromatic ring polymer, sulfone plastics are mainly three types: ordinary bisphenol A-type PSF (that is, usually referred to as PSF), polyarylsulfone and polyethersulfone.
2, PSU plastic raw materials for amber transparent solid material, high hardness and impact strength, non-toxic, heat and cold resistance aging resistance, can be in -100 - 175 degrees under long-term use. Resistant to corrosion of inorganic acids and alkali salts, but not resistant to aromatic hydrocarbons and halogenated hydrocarbons. Polyarylsulfone high hardness, radiation resistance, heat and cold resistance, and has a self-interested, can be used for a long time at -100 - 175 degrees.
3, in terms of radiation resistance for the good varieties of plastics.PSU plastic raw materials are easy to process molding, can achieve precision tolerances, in addition to concentrated nitric acid, concentrated sulfuric acid, other acids, alkalis, alcohols, aliphatic hydrocarbons, and other chemicals are stable.
PSUY use embodied aspects
1, daily necessities, PSU plastic material can be used to make humidifiers, hair dryers, clothing steam, camera cases, projector components and other heat and 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 adhesive, all with silane polysulfone such as PSU-SR, PKXR, etc. can be used as a binder for the sizing of glass fibers and graphite fibers to make composite materials, graphite fabrics reinforced with silane-based PSU can be made to lift the rudder and other aircraft parts. PSU in addition to the solid lubricant PTFE, can increase wear resistance and physical and mechanical properties, also used in the preparation of wear-resistant coatings;
2, electrical and electronic, PSU can be used for the production of a variety of contactors, connectors, transformer insulating parts, silicon cap, insulating bushings, coil bobbins, terminal blocks and collector rings and other electrical parts, printed circuit boards, bushings, hoods, TV system parts, capacitor film, brush holder, alkaline battery box, etc.;
3, kitchen supplies, PSU can be used instead of glass and stainless steel products used in the manufacture of steam trays, coffee containers, microwave cooker, milk and agricultural products containers, egg stove 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 new transparent material, heat water resistance, hydrolytic stability is better than any other thermoplastic, so it can be used to make coffee pots and so on. Connection tube made of PSU 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 lamp lamps;
4, health and medical equipment, PSU can be used to make surgical trays, nebulizers, humidifiers, contact lens fixtures, flow controllers, instrument covers, Dental instruments, liquid containers, pacemakers, respirators and laboratory equipment, etc. PSU used in the production of a variety of medical products than the low 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-filters, dialysis membranes, etc. PSU can be used for veneering, and its adhesive strength is twice as high as that of acrylic acid;
6, in addition to the PSU plastic materials can also be manufactured A variety of chemical processing equipment (such as pump covers, tower outer protective layer, etc.), food processing equipment, pollution control equipment, dairy processing equipment and engineering, construction, chemical piping and so on.
The above is what PSU is plastic raw materials and PSU uses the main embodiment.
