A polyol is an organic compound containing multiple hydroxyl (-OH) groups in its molecular structure. In the polyurethanepolyols play a crucial role as one of the two major components (the other being a diisocyanate) in the production of polyurethanes. These versatile polymers are used to create a wide variety of products including flexible foams and rigids, elastomers, adhesives, sealants, and coatings.
The polyols determine many of the physical properties of the polyurethane final, such as flexibility, toughness, and abrasion resistance. There are several types of polyols, including polyethers y poliésteres, cada uno con características únicas que los hacen adecuados para aplicaciones específicas. La selección del polyol adecuado es fundamental para obtener las propiedades deseadas en el producto de polyurethane end.
