Jiaxing Petrochemical, part of China’s Tongkun Group, has licensed Invista's P8 process technology for its second purified terephthalic acid (PTA) production line in Zhejiang Province, China.

The investment is designed to strengthen Tongkun's upstream and downstream business as well as increasing its risk resistance capacity, production scale and competitiveness.

Jiaxing Petrochemical's first PTA line, which came on stream in 2012, also licenses the process owned by Invista Performance Technologies (IPT). The former DuPont business licenses a number of technologies for production of a wide range of compounds in polyester, polyurethane and nylon value chains.
