PEI<\/strong><\/p>\n\n\n\n

PEI is composed of amorphous thermoplastic polyetherimide (Polyetherimide, abbreviated as PEI) material. The resin is transparent amber in color and has excellent high-temperature heat resistance, high rigidity and strength, as well as excellent chemical resistance.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Preparation Method and Molecular Structure<\/strong><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Polyetherimide is prepared by the thermal polycondensation, powder formation, and imidization of 4,4\u2032-diaminodiphenyl ether or m- (or p-) phenylenediamine with 2,2\u2032-bis[4-(3,4-dicarboxyphenoxy)phenyl]propane dianhydride in dimethylacetamide solvent.<\/p>\n\n\n\n

To improve the performance of PEI, it can also be further processed through continuous extrusion processes using extruders (such as blending with other polymers or fillers).<\/p>\n\n\n\n

Development History<\/strong><\/strong><\/p>\n\n\n\n

1<\/strong>972:<\/strong> GE in the United States began research and development of PEI.<\/p>\n\n\n\n

1982:<\/strong> GE built a 5,000-ton production facility and officially launched PEI under the trade name ULTEM in the market.<\/p>\n\n\n\n

2007:<\/strong> SABIC acquired GE\u2019s plastics division for USD 11 billion.<\/p>\n\n\n\n

2018:<\/strong> SABIC built a new PEI production line in Singapore, increasing production capacity by 50%.<\/p>\n\n\n\n

2022:<\/strong> The global polyetherimide (PEI) market sales reached RMB 2.6 billion and is expected to reach RMB 3.4 billion by 2029, with a compound annual growth rate of 4.3%. In 2022, the apparent demand for PEI plastics in China was USD 190 million, with a volume of 7,000 tons, an increase of 7.14% compared with 2022.<\/p>\n\n\n\n
