Polyols are a primary polyurethanes component. A polyol and an isocyanate react to form polyurethane. There are both polyether and polyester polyols. Polyether polyols are used in a wide range of rigid and flexible polyurethane applications, including energy-saving refrigeration insulation, industrial sealants, cushion foam, and construction and building materials. A polyether polyol and a polyfunctional isocyanate react to form polyurethane.
Polyols are most commonly used in the manufacture of flexible polyurethane foam, used in furniture, bedding and transportation, and in the production of rigid foams, which are used in construction materials, insulation, automotive components and more.
Polyols are combustible liquids and are toxic and harmful through inhalation, ingestion or skin and eye contact.
