The anticipated start up is in 2026.

According to the company’s website press release on April 27, 2023, This marks the second UNIPOL® PP technology reactor line that PetroChina Guangxi has licensed and the fifth that PetroChina Group has licensed from Grace for a total licensed capacity of 1,850KTA.
