Hanwha TotalEnergies Petrochemical is a comprehensive material and energy company that produces high value-added chemical and energy products. Since it was founded in 1988, we have led the growth of the petrochemical business in South Korea through technological innovations and by successfully executing a market expansion strategy. In 2003, we began building the foundation to become a global multi-material and energy company. We executed that plan by forming a joint venture with the TotalEnergies Group, a major French company in the energy and chemical industry. Since then, we have continued to lead South Korea's petrochemical market and grow as South Korea’s leading company through product innovations, strategic diversified investments, and economies of scale.


Our product portfolio includes monomers, such as ethylene, propylene, and butadiene. We also produce base chemicals like styrene monomer, paraxylene and ethylene glycol. With 20 plant units in the Daesan Petrochemical Complex, we can produce a wide range of products needed for energy, from gasoline, diesel, jet fuel and liquefied petroleum gas to polymers such as polyethylene, propylene, and EVA. We are the first company in South Korea to operate a naphtha-cracking center (a core facility in our petrochemical plant), a condensate fractionation unit (a refining facility) and an aromatics plant, all in a single complex. This complex represents a successfully organized vertical integration system-from sourcing to producing to distributing final products. The efficiency we’ve achieved with this system allows us to diversify our business portfolio and pursue stable growth.


Annually, we now produce 1.53 million tons of ethylene, 2 million tons of paraxylene, 1.04 million tons of styrene monomer and 1.12 million tons of polypropylene. In 2020, as part of expanding our high value-added products, we built an additional plant for ultra-high molecular weight polyethylene used as a secondary battery separator, which secured an annual production capacity of 140,000 tons. Our market dominance is built on a solid foundation, Globally, we hold the No. 1 market share in numerous markets, including solar grade EVA; HDPE used in bottle caps; EVA used in extrusion coating; flow mark free polypropylene (FMF PP) used in automotive composite materials; high isotactic polypropylene (HIPP) used in electronic applications; and protective polypropylene films for display products.


These products have been recognized as World Class Products by South Korea’s Ministry of Trade, Industry and Energy. To grow into a global leader in the material and energy industries, we plan to optimize operations by diversifying our raw materials. We will also strengthen high value-added products as we focus on expanding markets in the energy business. We expect to realize our vision by increasing sales of high value-added products and diversifying in the polymer business while boosting eco-friendly businesses by developing eco-friendly materials and technologies. Moving forward, in order to enhance our global competitiveness, we remain committed to leveraging synergies between our company and Hanwha Group's chemical and energy affiliates.
