About Hyundai Chemical, Co, Ltd

Hyundai Chemical was established from a strategic joint venture between Hyundai Oilbank and Lotte Chemical on May 20, 2014. Hyundai Chemical is manufacturing petroleum products such as LPG, naphtha, kerosene and diesel, etc., and petrochemical products such as MX and benzene, etc. using condensate as the raw material, and is planning to additionally manufacture petrochemical products such as polyethylene and polypropylene, etc. after the completion of HPC Project. HPC, unlike the competitors who use naphtha as the main raw material, has secured high cost competitiveness in comparison to the competitors by using Treated De-Asphalted Oil (T-DAO), Propane and by-product gas, etc., which are cheaper than naphtha, as the raw materials. Majority of products and by-products that Hyundai Chemical manufactures are sold to Hyundai Oilbank and Lotte Chemical, which are the stockholders, and Hyundai Cosmo, a subsidiary company of Hyundai Oilbank, under contract, thereby having secured stable revenue base and outstanding competitive advantages. As the first joint venture established by a domestic refinery and a petrochemical company, Hyundai Chemical will keep evolving into a global petrochemical company with cooperation between both companies.
