Product Families


Our chlor-alkali products include chlorine, which is used to make water safe to drink and for many construction-related products and is also used as a necessary component of most pharmaceuticals. OxyChem caustic soda is central to the production of pulp, paper and aluminum, and is used in battery recycling. Our caustic potash is a principal component in fertilizers, batteries, soaps and detergents and specialty glass. It will also be used in Oxy’s direct air capture facilities as part of our efforts to reduce atmospheric concentrations of carbon dioxide and help meet the goals of the Paris Agreement.


OxyChem’s vinyl products include polyvinyl chloride (PVC) resin used for water supply piping and a broad array of medical supplies, including IV bags and medical tubing, as well as long-lasting construction materials, including for use in direct air capture facilities. The company develops and licenses its vinyl-related technologies to qualified manufacturers around the world, and plants currently using these technologies constitute more than a third of the world's ethylene-based capacity for producing vinyl chloride.

Our chlorinated organics portfolio includes 4CPe, an OxyChem-developed and patented product used in next-generation, climate-friendly refrigerants with low global-warming and zero ozone-depletion potential.
