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 16,000 people, Westlake operates from locations in North America, Europe and Asia.  


Westlake is proud of who we are - a responsible manufacturer and global supplier of chemicals, polymers and building products. Our mission is to serve our customers by safely and reliably providing quality and sustainable products and services that enhance people's lives every day. Westlake works to align the interests of our global customers and suppliers with those of our shareholders, employees and the communities in which we operate. Safety and a vigilant stewardship of the environment is at the forefront of everything we do. We strive to be a low-cost manufacturer and to find value across the product chain through vertical and horizontal integration. Westlake adheres to the concept of Economic Value Added and seeks to return value to our shareholders above the invested cost of capital.   


Our core values are at the heart of how Westlake conducts business. These core values guide us as we work to bring excellence to our operations and customers and earn the respect of our communities. Our core values are:  


    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.
