Kingfa Sci. & Tech., 1,000-Ton Pilot PEI Line Put Into Production! Polyetherimide: Who Is Laying Out the Market, and What Is the Production Capacity?
Recently,Kingfa Sci. & Tech. Polyetherimide (PEI)There is new activity in the field!
On June 24, Kingfa Sci. & Tech. disclosed on the interactive platform.The company has established and put into operation a pilot production line for polyetherimide (PEI) with a capacity of 1,000 tons per year., currently in the small-batch sales stage, while simultaneously advancing polymerization process optimization, development of modified applications, market promotion, and industrialization process design. The products can be applied toElectronics and Electrical, Automotive, Medical, Communications, Aerospaceand other fields.

Industry insiders stated that the commissioning of the thousand-ton pilot production line
means that Kingfa Technology is entering
This niche market has long been dominated by overseas giants.
Although it is still in the small batch phase.
But the breakthrough from 0 to 1 has already been achieved.
What is polyetherimide (PEI)?
Polyetherimide (PEI) is a class of amorphous, amber-colored, high-performance thermoplastic engineering plastics.
It is known for its excellent characteristics such as high temperature resistance, dimensional stability, chemical resistance, flame retardancy, electrical properties, high strength, and high rigidity.The pinnacle of the plastics pyramidOne of the materials.
PEI was first developed by General Electric (GE) in the United States in 1972. In 1982, GE took the lead in commercializing PEI by establishing a 5,000-ton production facility and naming the product ULTEM™. In 2007, SABIC completed the acquisition of GE’s plastics division.
SABIC currently has three sites producing ULTEM™ resin.

"Who is laying out 'PEI'?"
Currently, globally, apart from SABIC, there areRTP, Ensinger, LyondellBasell, Mitsubishi Chemical Advanced Materials, AmerichemCompanies such as ... can provide modified and customized PEI products, and overseas manufacturers have long dominated the global PEI market supply.
Major domestic PEI resin producers, in addition to Kingfa Sci. & Tech., include Wanhua Chemical Group, Shanghai Synthetic Resin Research Institute, and Youju New Materials.
*The ranking of companies is not in any particular order.
Wanhua Chemical Group
(CECEP Wanrun Co., Ltd.)
Wanshun Co., Ltd. is the first company in China to achieve commercial production of PEI resin.It has already established a production capacity reserve of thousands of tons (the 1,500-ton annual production line has been put into trial production).。
Product models include PEI-VAT002, PEI-VAT002BK/BL/GN, PEI-VAT002HF, etc., and are widely used in fiber optic connectors, aerospace composites, automotive, semiconductor, and medical device fields.
