PSU(聚砜类塑料)P-1700NT11

1, polysulfone is amber transparent solid material, high hardness and impact strength, non-toxic, heat and cold resistance, good aging resistance, can be long-term use -100-175 degrees. Resistance to inorganic acid and alkali corrosion, but not resistant to aromatic hydrocarbons and halogenated hydrocarbons. Polysulfone high hardness, resistance to radiation, heat and cold is good and has self-interest, long-term use at -100-175 degrees.
2, through the glass fiber reinforced materials can be significantly improved wear resistance.
3, Polysulfone and ABS, polyimide, polyetheretherketone and fluoroplastic made of polysulfone modified products, mainly to improve its impact strength and elongation, solvent resistance, environmental resistance, processing Performance and platability. Such as PSF / PBT, PSF / ABS, PSF + mineral powder. 1, suitable for the production of heat-resistant parts, insulating parts, wear-resistant wear parts, instrumentation components and medical equipment parts, poly aryl sulfone suitable for the production of low-temperature working parts.
2, polysulfone in the electrical and electronic industry commonly used in the manufacture of integrated circuit boards, coil racks, contactors, shelves, capacitor film, high-performance alkaline battery case.
3, polysulfone in the household appliances for microwave oven equipment, coffee heaters, humidifiers, hair dryer, cloth steam dryer, beverage and food dispensers. Can also be used instead of non-ferrous metals watches, photocopiers, cameras and other precision components.
4, polysulfone has passed the United States medicine, food specifications in the field, can replace stainless steel products. As polysulfone resistant to steam, hydrolysis, non-toxic, high temperature steam sterilization, high transparency, good dimensional stability and other characteristics, can be used as a surgical tool tray, sprayer, fluid controller, heart valve, pacemakers, gas masks, Dental care and so on.
Forming properties 1. Amorphous material, moisture absorption, water absorption 0.2% -0.4%, before use to be fully dried, and to prevent moisture absorption. Guarantee water content below 0.1%.
2. Forming properties and PC similar, poor thermal stability, began to decompose when 360 degrees.
3, poor liquidity, fast cooling, should be high temperature and pressure molding. Die should have sufficient strength and stiffness, set cold material wells, runners should be short, the gate size to take the plastic wall thickness of 1 / 2-1 / 3
4. To reduce the internal stress generated by injection molding, mold temperature should be controlled at 100-140 degrees. After the annealing can be taken to shape glycerol bath annealing, 160 degrees, 1-5 minutes; or take an air bath 160 degrees, 1-4 hours. Annealing time depends on the product size and wall thickness.
5. Polysulfone in the molten state close to the Newtonian body, similar to the polycarbonate, from the mobility of the more sensitive to temperature in the 310 degrees -420 degrees, the temperature increased by 30 degrees, the mobility increased by 1 times. Therefore, molding mainly by improving the temperature to improve the processing of liquidity.
