US PVC resin and chlor-alkali manufacturer (NYSE: WLK, HQ Houston TX; ~$13B revenue); the world's largest PVC resin producer and North America's dominant supplier. Westlake acquired Axiall Corporation in 2016 for $3.8B, combining Axiall's chlor-alkali and PVC resin capacity with Westlake's ethylene and VCM operations. Westlake operates integrated PVC plants in Lake Charles, Louisiana (multiple trains) and Sulphur, Louisiana — the largest PVC resin complex in the US by volume, accounting for approximately 28% of US PVC resin capacity. Westlake's PVC resin is the primary feedstock for pipe, siding, window profiles, and wire insulation. The Lake Charles complex sits within the largest concentration of chlor-alkali/VCM/PVC production in the Western Hemisphere. Westlake also makes epoxy resins, caustic soda, and chlorine — the chlor-alkali co-products that finance PVC resin production economics.
