Westlake Chemical Partners LP is a master limited partnership formed in July 2011 by Westlake Chemical Corporation to own, operate and acquire chlor-alkali and vinyl production assets. Through its lease and purchase agreements with its general partner, Westlake Chemical Partners holds interests in multiple chemical production facilities that produce key building blocks for a wide range of downstream products. The partnership’s structure provides it with dedicated cash flow streams from long‐term contracts with its sponsor, allowing a focused management of its core vinyls portfolio.
The company’s principal products include ethylene dichloride (EDC), vinyl chloride monomer (VCM), caustic soda (sodium hydroxide), chlorine and hydrochloric acid. EDC and VCM are critical intermediates in the manufacture of polyvinyl chloride (PVC) resin, which is used extensively in construction, automotive and packaging applications. Caustic soda and chlorine serve diverse markets in pulp and paper, water treatment, metal processing and consumer goods. Westlake Chemical Partners is also engaged in the merchandising and distribution of these chemicals, leveraging an integrated logistics network of pipelines, barge terminals, railcars and trucking fleets.
Geographically, Westlake Chemical Partners operates major facilities in Sulphur, Louisiana, and Calvert City, Kentucky, with access to key feedstocks such as ethylene, salt and natural gas by‐products from regional petrochemical complexes. Its sites are linked to the U.S. Gulf Coast’s energy corridor, enabling efficient feedstock supply and product shipments to domestic and export markets. The partnership’s logistics infrastructure supports deliverability to manufacturers throughout North America, with supplemental export opportunities to Latin America and Asia Pacific.
Leadership at Westlake Chemical Partners combines seasoned industry executives with deep operational expertise in chlor‐alkali and vinyls production. The partnership’s board and management team are responsible for overseeing asset performance, safety, environmental compliance and strategic growth initiatives. As a growth‐oriented MLP sponsored by Westlake Chemical Corporation, Westlake Chemical Partners benefits from the sponsor’s technical know‐how, financial support and commitment to operational excellence in the specialty chemicals sector.
