Companies that use chemicals containing PFAS (per- and polyfluoroalkyl substances) could face sizable legal issues as these materials continue to face mounting regulatory scrutiny. PFAS comprise unique physical and chemical properties to create a water repellency and are commonly used in coatings for textiles, paper products, food packaging, cookware, firefighting foams, carpets, outdoor sportswear and more.
