SCG Chemicals (also branded as SCGC) is one of Asia’s largest integrated petrochemical producers and the core chemicals arm of The Siam Cement Public Company Limited (SCG), a leading industrial conglomerate headquartered in Thailand. The company operates across the full petrochemical value chain, from upstream olefins to downstream polymers and specialty solutions, with a growing focus on sustainability and high‑value applications.
Corporate Overview
SCG Chemicals is a wholly owned subsidiary of SCG and forms one of its three main business units alongside cement–building materials and packaging. Established with its first polyethylene plant in 1989, the company has since expanded into a major regional player with integrated, world‑scale operations centered in Map Ta Phut, Rayong Province, Thailand.
SCG Chemicals positions itself as a “Chemicals Business for Sustainability,” emphasizing innovation, operational reliability, and regional leadership in petrochemicals and advanced materials. The company markets its products globally, serving customers in Asia-Pacific and beyond in sectors such as packaging, automotive, construction, energy, and healthcare.
Business Portfolio
SCG Chemicals’ portfolio spans upstream, intermediate, and downstream segments, with a broad range of petrochemical products.
-
Upstream and intermediate products include olefins such as ethylene and propylene, which feed downstream polymer production.
-
Downstream polymers cover polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and related plastics used in films, pipes, rigid and flexible packaging, and consumer goods.
-
The company also develops high value-added (HVA) products and solutions in areas like infrastructure, consumable packaging, mobility, medical and well‑being, and energy solutions, integrating material innovation with application development.
Beyond core petrochemicals, SCG Chemicals has built ancillary businesses linked to energy and efficiency, including floating solar solutions, clean energy systems, and emisspro® furnace coating technologies aimed at improving industrial energy performance.
Geographic Footprint
SCG Chemicals’ main production hub is in Map Ta Phut, one of Southeast Asia’s largest petrochemical complexes. From this base, the company operates integrated plants that convert feedstocks into olefins and further into a diverse slate of polymers and specialty materials.
The company has extended its footprint through joint ventures and subsidiaries across the region, supporting both production and downstream application development. This regional network allows SCG Chemicals to serve key markets in ASEAN and broader Asia-Pacific, leveraging proximity to fast‑growing consumer and industrial demand centers.
Partnerships and Joint Ventures
SCG Chemicals has long pursued a partnership-driven growth model, forming joint ventures with major international petrochemical companies.
