PTTGC and SCGC are studying a joint venture combining their Thai polyethylene (PE) and polypropylene (PP) businesses, with a reported value of about 60,000 million baht. The first feasibility stage should show clarity around late September 2026. If it proceeds, setup would take about 13-15 months. The combined firm would hold over 6 million tonnes of resin capacity and roughly 60% of Thai PE, so resin buyers and converters may face less price competition over time. For most small Thai businesses this is background only; no action is needed before the September result.
