Westlake Chemical

Westlake Chemical’s Lake Charles Complex started in 1986 when T.T. Chao—a pioneer in the global petrochemical industry—and his sons acquired a shut-down polyethylene plant in Lake Charles. Thirty years later, in 2016, Westlake acquired Axiall Corporation, which doubled the company in size. Westlake’s Lake Charles Complex now consists of four production sites, plus a marine terminal, and produces ethylene, polyethylene, caustic soda, chlorine, styrene and other coproducts.

Westlake Chemical is the largest petrochemical employer in Calcasieu Parish and the second largest petrochemical employer in Louisiana with approximately 1,800 employees working in Calcasieu Parish.

The Petrochemical Complex contains two ethylene production plants, a styrene monomer plant and two polyethylene plants.  This site employs approximately 370 employees and core contractors.

The Polymers Complex contains five polyethylene manufacturing lines, and employs approximately 275 employees and core contractors.


The Westlake North VCM facility, former Axiall site, contains one VCM plant and employs approximately 120 employees and core contractors.

The Westlake South VCM facility, former Axiall site, contains two chlor-alkali plants which produce chlorine and caustic soda; one derivatives plant that makes vinyl-chloride monomer (VCM) and ethylene dichloride (EDC), among other products. The site also has four power generation houses. The Westlake South Complex employs approximately 1,240 employees and contractors, and is the company’s largest site.

Westlake employees produce chemicals that are used in products which enhance the lives of many people every day, ranging from bread bags to toys to medical containers.

At the Petro and Poly sites, ethylene is the key building block chemical that is used to produce styrene and polyethylene, which can be used to make food packaging, carton liners, toys, polyester resins, trash bags, paints, building materials and thousands of other products.

At the North and South sites, feedstock from the plant helps produce VCM, which is an important feedstock for making vinyl siding, PVC piping and other building products. The South facility transforms salt water from the Sabine River into chlorine and caustic soda, which becomes essential ingredients to produce a variety of products used on a daily basis, such as chlorine tablets for swimming pools, Drano, computer paper, toilet paper and much more.

In addition to producing these products, Westlake Chemical has a strong commitment to safety and community involvement. The Westlake Petro and Poly facilities are OSHA VPP Star Sites, indicating the injury rate is well below the national average in our industry.

Westlake Chemical employees are active in the community, supporting a vast array of activities and initiatives, ranging from Partners in Education, The United Way of Southwest Louisiana, Big Brothers Big Sisters of SWLA, Abraham’s Tent, Special Olympics, Junior Achievement, Trash Bash, CHRISTUS St. Patrick Hospital Dragon Boat Races, American Cancer Society, McNeese State University Foundation, the St. Nicholas Center for Autism, United States Postal Service Food Drive, to many more.
