In 1972 SK Corp. built the sector's first naphtha-cracking plant with an annual capacity of 100,000 tons, which helped lay a cornerstone for Korea's petrochemical industry. From that time on, SK Corp. has invested in improved equipment and technological innovation. Currently, SK Corp. seeks to maximize profits by introducing multipurpose commodity lines while concentrating on high-performance specialty chemicals and high-value compounds. The company has opened its www.skchem.com site to activate e-commerce and provide customers with information updates. With this e-commerce foundation, the full status of processing from manufacturing lines and online orders to delivery can be accessed in one see-it-all site, allowing efficient one-stop customer service. With cost and quality competitiveness, we will continue to expand our domestic market and diversify our export market by keeping pace with innovations in technology and service.
