JG Summit Olefins Corporation (JGSOC) is a pioneer in the petrochemical industry in the Philippines, with its fully integrated manufacturing complex in Batangas City. Previously there were two subsidiaries, JG Summit Petrochemical Corporation (JGSPC) established in 1994, which operated the polymer facilities, and JGSOC established in 2008, which operates the naphtha cracker plant. These two companies were collectively known as the JG Summit Petrochemicals Group (JGSPG). As of January 1, 2022, the two companies have been merged to a single corporate entity, with JGSOC as the surviving entity of the merger.JGSOC operates the first and only naphtha cracker plant in the country, which produces the olefin raw materials ethylene and propylene used as feedstock by the downstream polymer plants. The cracker's products also include pyrolysis gasoline or ‘pygas' and mixed C4, which are in turn the raw materials to produce C4 olefins and aromatics products from its butadiene and aromatics extraction plants, respectively.
