Blending our chemical capabilities with a strong, downstream building products business, Westlake delivers life-enhancing products that benefit lives every day.? From our polyethylene that is used daily in food packaging like bread bags, cheese wrapping and milk cartons, to our PVC pipe which is used to deliver clean drinking water or to irrigate fields, our products make a difference in the world.??

Employing approximately 9,500?people, Westlake operates from 36?locations in North America, 11 in Europe and 6 in Asia.? Our unwavering goal is to provide quality products and service to our customers?by being highly responsive, reliable, nimble and easy to work with.??


Our mission is to provide quality products and services to commodity chemical, plastics and related fabricated products markets. We work to align and focus the interests of our global customers and suppliers with those of our shareholders, employees and communities. We strive to be a low cost manufacturer and to find value across the chain through vertical integration and synergies through horizontal integration. We adhere to the concept of economic value added?(EVA°) and seek to return value to our shareholders above their invested cost of capital.


Our core values are at the heart of how we conduct our business and serve to guide each of us as we work to bring excellence to our operations, customers and communities.?


    The health and safety of our employees and communities, and the vigilant stewardship of the environment and sustainability are of utmost importance and at the forefront of everything we do.


    Our commitment to quality products and service is so strong that both are symbolized as the two check marks that form the Westlake “W” in our logo.? We seek to maintain this commitment through an intensive practice of “never-ending process of improvement."


    We recognize the importance of supporting the communities in which we work and live and make it a priority to take an active role in making these communities better.
