Nouryon invests in multiple polymer capacity expansions in China
Nouryon announced important investments in China to support the country’s increasing demand for high-performance polymers.



To mark Nouryon’s milestones in China, the company hosted an event at its Jiaxing site.
The company has completed a capacity expansion for metal alkyls production at its site in Jiaxing, China. This will ultimately double its ability to produce triethylaluminum, a co-catalyst essential in the manufacture of polyethylene and polypropylene for packaging, automotive components and consumer goods.
In 2027, Nouryon will also begin producing modified methylaluminoxane (MMAO) in China, a key component in catalysts for polyolefin elastomers used in solar panels, which is another rapidly growing segment in China.
Additionally, in 2026, the company will open an organic peroxides innovation center in Tianjin to provide specialized polymer application capabilities for faster product development and enhanced customer support.
These developments further strengthen the strategic importance of Nouryon’s Jiaxing site, which already houses an R&D laboratory established in 2024. The lab focuses on improving process efficiency and pioneering new production methods for metal alkyls, playing a vital role in supporting polyolefin innovation and regulatory alignment in China.
These projects fall under Nouryon’s Performance Materials segment within its Polymer Specialties business unit.
Nouryon operates a global network of metal alkyl production sites in La Porte, Texas, US; Rotterdam, Netherlands; and Jiaxing, China. The company also operates metal alkyl application centers in Deventer, Netherlands; and Jiaxing, China, and transfilling and blending stations in Jiaxing, China; Paulínia, Brazil; and Mahad, India.
