Siam Synthetic Latex Company Limited is a Thai petrochemical manufacturer focused on synthetic latex and specialty elastomers. Incorporated in 1990 and headquartered in Bangkok, it operates production facilities primarily in the Map Ta Phut Industrial Estate in Rayong Province, with additional operations in the Asia Industrial Estate.
The company produces styrene-butadiene latex (SB latex) and polyolefin plastomers and elastomers, including the AFFINITY™ and ENGAGE™ product lines. These materials serve applications in adhesives, coatings, paper, textiles, packaging, and polymer modification, with sales extending across Thailand and international markets in the Asia-Pacific region and beyond.
It operates as a 50/50 joint venture within the SCG-Dow Group, equally owned by SCG Chemicals Public Company Limited (SCGC, part of the Siam Cement Group) and The Dow Chemical Company, with operations managed by Dow. This positions the company as an integral part of Thailand's Map Ta Phut petrochemical cluster and the broader SCG-Dow collaboration in downstream chemicals.
As a relevant joint venture of SCGC, its shares have been referenced in strategic discussions, including the 2026 progress update on a potential olefins and polyolefins joint venture between SCGC and PTT Global Chemical.
