PSU plastic (Polysulfone) :Polysulfone Specific gravity :1.25-1.35 g\/cm 3 Molding shrinkage :0.5-0.7% Molding temperature: 290-350℃ Drying conditions: 1, polysulfone is amber transparent solid material, high hardness and impact strength, non-toxic, heat and cold resistance good aging resistance, can be used for a long time at -100--175 degrees. Resistant to inorganic acid, alkali and salt corrosion, but not resistant to aromatic hydrocarbons and halogenated hydrocarbons. Polyarylsulfone has high hardness, radiation resistance, good heat and cold resistance and self-breathability, and can be used for a long time at -100-175 degrees. 2, through glass fiber reinforced modification can greatly improve the wear resistance of the material. 3, polysulfone and ABS, polyimide, polyether ether ketone and fluorine plastics can be made into modified products of polysulfone, mainly to improve its impact strength and elongation, solvent resistance, environmental resistance, processing performance and electroplating ability. Such as PSF\/PBT,PSF\/ABS,PSF mineral powder. 1, suitable for the production of heat-resistant parts, insulation parts, wear resistant parts, instrument parts and medical equipment parts, polyarylsulfone suitable for the production of low-temperature working parts. 2, polysulfone in the electronic and electrical industry is often used in the manufacture of integrated circuit boards, coil tube frames, contactors, sleeves, capacitive films, high-performance alkaline battery shells. 3. Polysulfone is used in household appliances for microwave oven equipment, coffee heater, humidifier, hair dryer, cloth dryer, beverage and food dispenser, etc. It can also replace non-ferrous metals for precision structural parts such as clocks, copiers, cameras, etc. 4, polysulfone has passed the relevant norms in the field of medicine and food in the United States, and can replace stainless steel products. Because polysulfone is resistant to steam, hydrolysis, non-toxic, high temperature vapor disinfection, high transparency, good dimensional stability, it can be used as surgical tool tray, sprayer, fluid controller, heart valve, pacemaker, gas mask, dental base and so on. 1. Amorphous material, large moisture absorption, water absorption rate of 0.2%-0.4%, must be fully dried before use, and prevent moisture absorption. Keep the water content below 0.1%. 2. Molding performance is similar to PC, poor thermal stability, decomposition begins at 360 degrees. 3. Poor fluidity, fast cooling, suitable for high temperature and high pressure molding. The mold should have sufficient strength and stiffness, set a cold feed well, the flow channel should be short, and the gate size should be 1\/2-1\/34 of the wall thickness of the plastic parts. In order to reduce the internal stress generated by injection molded products, the mold temperature should be controlled at 100-140 degrees. After forming, it can be annealed with glycerol bath, 160 degrees, 1-5 minutes; Or take an air bath of 160 degrees for 1-4 hours. The annealing time depends on the size and wall thickness of the product. 5. Polysulfone is close to Newtonian body in the molten state, similar to polycarbonate, and the fluidity is more sensitive to temperature, in 310-420 degrees, the temperature increases by 30 degrees, the fluidity increases by 1. Therefore, the processing fluidity is mainly improved by increasing the temperature during molding.
PSU is an amber transparent solid material with a density of 1.25 to 1.35 g\/cm3. Polysulfone is an excellent engineering material with high modulus, high strength, high hardness, low creep, heat resistance, cold resistance, aging resistance and other characteristics. The embrittlement temperature is -101℃, and the thermal deformation temperature is about 175℃ at 1.82MPa. In the actual test, there was no significant change in performance at 150℃ for 2 years.
