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



As the world’s most widely used polymer, polyethylene enables converters to design innovative packages and make performance improvements to countless products that enhance our lives every day – from packaging films that protect against impact and temperature extremes, coatings and adhesives used in cartons engineered to transport perishable foods without refrigeration, to medical films and personal care products supporting public health.
