Thailand's two major petrochemical players—PTTGC (PTT subsidiary) and SCGC (SCG subsidiary)—are studying a joint venture worth ~600 billion baht to merge olefins and polyolefins operations. The combined entity would have 6 million tonnes of plastic pellet capacity (PE and PP) and become globally competitive. Feasibility clarity expected end-September; if approved, 13–15 months needed for final setup. This addresses survival pressures from global overcapacity and rising competition, leveraging PTTGC's upstream gas/supply network with SCGC's downstream R&D strength to secure Thai market share (60%+ PE, ~25% PP) and position for international scale.
