Westlake vinyl resin products are the key ingredients to making some of the world’s most prevalent items, including residential siding, pipe and fittings for various water, sewer and industrial applications, and PVC profiles for windows, doors, fence, deck and rail applications. Our principal products in our integrated Vinyls segment include PVC, VCM, EDC, Chlorine, Caustic Soda and Ethylene. 

We supply PVC resin to three Westlake companies.   Our North American Pipe and North American Specialty Products manufacture PVC pipes and fittings, and Westech Building Products fabricates rigid profiles for residential construction including decking, railing and fencing as well as for windows and patio doors. 

Vinnolit, our most recent acquisition, expanded our portfolio to add important specialty PVC resin products and technologies.
