Aekyung Petrochemical is a specialty chemicals company organized into four strategic business segments—plasticizers, synthetic resins, household chemicals, and bio-energy—following the 2021 merger that absorbed Aekyung Chemical and AK Chemtech into the current structure.
The plasticizer segment, its largest at 47.6% of revenue, produces phthalic anhydride, plasticizers, and lubricant base oil, and the company is known as Korea's leading plasticizer producer.
The synthetic resin segment (12.8%) handles unsaturated polyester resin, coating resins, and hardeners supplied to paints, electronic materials, and LNG carrier insulation. The household chemicals segment (20.9%) produces surfactants (AOS, SLES, LAS) and refined glycerin used in laundry detergents and cleaning agents.
The bio-energy segment (16.1%) makes biodiesel and bio heavy oil alongside hard carbon for secondary battery anode materials, with the company positioned as Korea's only hard carbon manufacturer.
More recently, the company internally developed and commercialized TPC (terephthaloyl chloride), the core precursor for aramid fiber, as a new business line—a domestic first.
The controlling shareholder is holding company AK Holdings, while affiliate Aekyung Industrial operates separately in cosmetics and household products.
Competitively, plasticizers and household chemicals face intensifying price competition from Chinese producers in commodity-grade products, prompting the company to pursue a portfolio shift toward higher value-added specialty materials such as TPC and hard carbon.
