At present, seven manufacturing facilities under SCG-DOW Group, a joint venture of equal equity between SCG Chemicals Co., Ltd. and Dow Chemical, are operated and managed by Dow Chemical as follows:
First launched at Phra Pradaeng in 1978 as the first domestic polystyrene manufacturer, the plant was moved to Map Ta Phut and re-launched in 1995. Its feedstock is supplied by an on-site associate company (Siam Styrene Monomer Co., Ltd.) to produce a versatile plastic found in a wide range of everyday products. High-quality polystyrene manufactured by Siam Polystyrene Co., Ltd., finds applications in medical instruments, consumer electronics and electrical appliances, telecommunications, toys, office equipment, and numerous household items.
Started up in 1993, the plant leverages Dow’s latest technology with fully automated production process control along with bulk raw-material facilities, a sophisticated quality control laboratory and a full-fledged paper latex application laboratory to support the local paper industry and paper latex development. New technical improvements yield up-to-date technology every year. Dow is using styrene monomer derived from Dow’s own Styrene Monomer and Ethylbenzene Plant and butadiene derived from a local producer transmitted by pipeline within the Map Ta Phut complex. Styrene-butadiene finds applications in the production of high-quality coated paper and paperboard, carpet backing, concrete modification for the construction industry, binders for architecture paint, and paper and packaging industry such as toothpaste or soap boxes.
Another first and foremost in Thailand, this plant came on stream in 1997, processing from benzene and ethylene into high-quality styrene monomer, supplying to our own polystyrene and styrene-butadiene latex plants. Styrene is also sold to local external customers as well. Together with the polystyrene plant, the plant supports national development by using locally manufactured raw materials to produce intermediate and finished products for domestic and re-export markets.
With its first train started up in 1999, this plant produces linear low-density polyethylene (LLDPE) for the manufacture of assorted items for everyday use, including stretch cling film, food overwrap, detergent bags, laminated tubes, heavy-duty bags, agricultural film, and as a sealant layer for flexible food packaging. LLDPE also finds applications in rotational molding, found in household articles and toys that demand extra durability.
For greater operating efficiency, broader product coverage, and faster response to customers’ needs, Dow established the second solution polyethylene train in 2010. This was also the first polyethylene plant with an ABB 800xA process automation system, containing Dow-developed software. Highly integrated with the existing plant, this new plant leveraged the knowledge and expertise from the first.
Started up in 2011, this plant supplies customers in this fast-growing region with some of the most technologically advanced elastomers in the world. Versatile AFFINITY™ polyolefin plastomers offer excellent adhesion at high and low temperatures, excellent processability, and superior performance in packaging and other applications. ENGAGE™ polyolefin elastomers offer an exceptional combination of flexibility and toughness, making them a material of choice for diverse applications, including automotive thermoplastic applications.
On stream since 2011, this is the second plant worldwide that relies on the innovative hydrogen peroxide to propylene oxide (HPPO) technology. Jointly developed by BASF and Dow, the breakthrough technology enables production of propylene oxide without styrene monomer as a by-product while avoiding the formation of other by-products, thus significantly reducing wastewater generation. This technology was internationally recognized with an Innovation and Excellence Award in Core Engineering from the Institution of Chemical Engineers, headquartered in the United Kingdom and 2010 Presidential Green Chemistry Challenge Award from the U.S. Environmental Protection Agency.
Propylene oxide serves as feedstock for various industrial products, including polyurethanes, propylene glycols, and glycol ethers, used for insulation, furniture, personal care products, and brake fluids.
