United States-based Ticona Engineering Polymers, a business of Celanese Corp., has begun operations
at its GUR® ultra-high-molecular-weight polyethylene (UHMW-PE) manufacturing facility located at
the Celanese integrated complex in Nanjing, China. The 20,000-ton-capacity facility joins Ticona’s
GUR facilities in Germany and Bishop, Texas, to bring the company’s total global GUR production
capacity to 90,000 metric tons.

customers in this region of impressive growth,” said Sandra Beach Lin, president, Ticona.

Ticona’s new facility is part of a multi-year investment to expand the company’s product and
resource offerings to its customers in the Asian region. Plans include construction of other
manufacturing sites in China for the production and research and development of advanced engineered
polymers and compounds.
