Development status and trend of polysulfone resin

The development status and trend of polysulfone resin in the world

the lightweight problem of new energy vehicles has been alleviated to a certain extent. Polysulfone resin is a thermoplastic engineering plastic prepared by polycondensation with bisphenol A and 4,4 '- dichlorodiphenylsulfone as raw materials, which is called PSF for short. Polysulfone material has good rigidity and toughness, temperature resistance, heat resistance and oxidation resistance. It can be used for a long time in the temperature range of - 100 ℃ and - 150 ℃ as shown by the investment heat of 28 bulk commodities in 2017. It has excellent creep resistance, resistance to the corrosion of inorganic acids, alkalis and salt solutions, resistance to ionic radiation, non-toxic, good insulation and self extinguishing size greater than 50cm longer and wider than the base of the experimental machine. It is easy to form and process, and can be widely used in aerospace, aviation Electronic and electrical, hollow fiber, polymer functional films, food containers, medical devices, textile machinery, household appliances, automobiles and other fields

polysulfone materials were first successfully developed and put into production by United Carbide Corporation (UCC). However, in 1986, the company transferred all its polysulfone production and sales rights to Amoco at that time. At present, the main polysulfone manufacturers include BASF, ICI and Russia's Shevchenko factory. There are more than 60 brands of various polysulfone products. The global total production capacity is about 35000 tons/year, and the total consumption is about 30000 tons/year. It is estimated that by 2005, the global consumption of polysulfone resin will reach more than 40000 tons

at present, the main consumer markets of polysulfone products in the world are concentrated in the United States, Japan and Europe. In terms of use, the consumption in aerospace and automotive fields accounts for 32%, electronics and electronics 36%, precision machinery 10%, food industry 8%, industrial devices 8%, medical devices 4%, and other fields 2%. Among them, in the aerospace and automotive industries, polysulfone materials are mainly used for the production of aircraft inner and outer rudder components, lamp shading plates, hoods, gears, electronic ignition devices, astronaut mask shielding devices, etc; In the electronic and electrical field, it is mainly used to produce printed circuit board substrate, integrated circuit board carrier, potentiometer, contactor, capacitor film, video recorder and recorder components, etc; In the field of household appliances, polysulfone materials can be used to produce microwave oven equipment, dryer, food cooking equipment, camera and projector shell, etc; In the field of medical devices, it can also be used in the production of medical device instrument housings, surgical panels, pacemakers, dental appliances and surgical equipment for internal and external medicine

in the development of polysulfone modified materials, in addition to glass fiber reinforced high rigid polysulfone composites, many high-performance polysulfone alloys have been developed internationally, such as polysulfone/polyamide, Polysulfone/rubber, polyethersulfone/Polyphenylene Sulfide and polyethersulfone/polycarbonate. Sumitomo has found that adding polytetrafluoroethylene and hydroxybenzoate to polyether sulfone can greatly improve the elastic modulus and wear resistance of the material; The Polysulfone/polyetherketone block copolymer developed by BASF has good chemical corrosion resistance and high temperature resistance; If you want to improve the flame retardancy of polysulfone materials, you can add 0.5% brominated polyphenylene oxide to polysulfone products to obtain transparent flame retardant products with flame retardant grade of v--0

the research of polysulfone resin in China began in 1967. At present, the annual production capacity is 1500 tons, and the output is generally maintained at about 1000 tons. In China, polysulfone resin has few brands and is mainly used in medical devices, food processing machinery, electronic instruments, textiles and other industries. Compared with foreign countries, China's polysulfone products not only need to be further improved and improved in the production process, including monomer synthesis, polymerization, post-treatment and recovery, but also need to be further promoted in the automotive industry, aerospace and other fields. In the future, we should vigorously develop new varieties of polysulfone materials, especially polysulfone alloys, nano polysulfone materials and membrane products, and continue to expand their application fields, so as to make greater contributions to the development of China's economy and technology in the new century
