IRPC Public Company Limited is a chemical manufacturer anchored by a fully integrated petrochemical complex in Rayong, Thailand. The company traces its origins to 1978 and began producing petroleum and petrochemical products in 1982, later becoming a public company in 1994 and listing on the SET in 1995, with rehabilitation completed in 2006. The complex is the first fully integrated petrochemical facility in Southeast Asia and is supported by in-house assets such as a deep-sea port, a tank farm, and a power plant.
IRPC serves customers in the petrochemical and related industries by producing a range of petroleum and petrochemical products through its integrated operations. In 2026, IRPC divested its entire 40% stake in WHA Industrial Estate Rayong Co., Ltd. to WHA Industrial Development Public Company Limited, reflecting an asset reallocation.
