Polyurethane is a petroleum-based polymer that was first developed by IG Farben in 1937. It can be manufactured in many different forms, which include high-resilience foam seating, surface coatings, and coated fabrics. Polyurethane coated fabrics are often used for faux leather, which is a cost-effective and popular material used for fashion and furniture upholstery, as well as in the automotive industry. While it does not contain phthalates, untreated polyurethane faux leather does not resist light, water, or heat, and will degrade over time. Polyurethane is also often used as protective topcoat for flooring, and is abrasion-resistant and known for its shine and long lifespan.
