Westlake manufactures two primary petrochemicals within the Olefins business segment – ethylene and styrene monomer. Most of our ethylene production supplies our internal needs in the polyethylene and vinyls businesses.

Westlake ethylene also supplies our styrene plant, which produces the primary raw material for polystyrene, coatings, unsaturated polyester resins and other derivatives. We also have implemented the most modern safety and environmental technologies to reduce emissions well below regulated levels and ensure the safety of our employees and surrounding community.
