​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, to our caustic soda which is used in pulp and paper manufacturing like carton boxes, our products make a difference in the world.  With our core value of being a good corporate citizen in our local communities, we are committed to being a leader in sustainable practices and a responsible environmental steward.
