Evonik and thyssenkrupp Industrial Solutions are licensing their HPPO technology for the production of propylene oxide to the Chinese chemical company Zibo Qixiang Tengda Chemical. The parties signed the contracts in Guangzhou, China, at the end of July.
thyssenkrupp will be responsible for the process design and supply key components for the new plant. In addition, Evonik is licensing hydrogen peroxide (H2O2) technology to Qixiang Tengda for the exclusive supply of the propylene oxide plant. The partners have also signed a long-term supply contract for the corresponding HPPO catalyst.
Propylene oxide is mainly used for the manufacture of polyurethane foams, which are used for example in automobile components, upholstery, thermal insulation, coating materials, sports shoes and other sporting goods. The global polyurethane market is set to grow by three to five percent annually up to 2025 and China is one of the most important growth markets.
