Polyaryl ether sulfone is a special engineering plastic that China's key research and development plan proposes to focus on. It is widely used in electrical and electronic, aerospace, automotive, food contact appliances, medical equipment and other fields. Because of its golden color, high temperature resistance, " Gold plastic" reputation.
Due to high technical barriers, the global market of polysulfone plastics has been monopolized by multinational chemical giants.
In 2015, with GDYJ's advanced new material technology Corporation's annual production line of 5,000 tons of polyarylethersulfone officially put into operation, GDYJ has become one of the world's major suppliers, and the global supply pattern of polyarylethersulfone has also changed.
As a special engineering plastic, polyarylethersulfone mainly includes three types: polyphenylsulfone (PPSU), polysulfone (PSU) and polyethersulfone (PES). Compared with other engineering plastics, polyarylethersulfone has excellent mechanical properties, chemical resistance, weather resistance properties, self-flammability, etc.
Therefore, polysulfone materials are widely used in consumer electronics, aerospace, automotive, medical equipment and other fields.
Among them, traditional fields such as electronics, automobiles, aerospace, and food are the main applications, with a total share of more than 70%.
In addition, the demand for polysulfone membranes in high-end applications such as biomedicine, fuel cells, and sewage treatment is also rapidly increasing.
After 10 years of innovation and development, GDYJ has become one of the few companies in the world after Solvay in Belgium and BASF in Germany that simultaneously owns PPSU, PSU and PES three series of polyaryl ether sulfone products and produces them on a large scale.
At present, GDYJ has three production bases in China, with a total production capacity of 8,000 tons of polyaryl ether sulfone production lines.
At the same time, special engineering plastic products such as polyetherimide (PEI), transparent aramid (PEA), liquid crystal polymer (LCP) and high temperature nylon (PPA) achieved commercial production.
The company's products have made significant breakthroughs in the application of polysulfone membranes in major high-end applications.
The company developed polysulfone membranes for hemodialysis and filter elements for treating polysulfone membranes and have achieved commercial production.
