Westlake manufactures and supplies products within two primary segments – olefins and vinyls. Our offerings contribute to some of the most vital and widely used products in the world, from car parts to bread bags to residential fences.

Within our vinyls segment we operate two subsidiary companies, which manufacture and market end-user industrial and consumer products. North American Pipe makes PVC pipe for water, sewer, irrigation and conduit applications. Westech Building Products makes PVC decking and fencing as well as profiles for windows and patio doors.
