In contrast to other common polymers such as polyethylene and polystyrene, polyurethane refers to a group of polymers. Unlike polyethylene and polystyrene, polyurethanes can be produced from a wide range of starting materials, resulting in various polymers within the same group.
Polyurethane, any of a class of synthetic resinous, fibrous, or elastomeric compounds belonging to the family of organic polymers made by the reaction of diisocyanates (organic compounds containing two functional groups of structure ―NCO) with other difunctional compounds such as glycols.
Polyurethane is a typical thermoset polymer compound characterized by durability, flexibility, toughness, and resistance to abrasion, acids/alkalis, solvents, and weathering. It is formed through a covalent polymerization reaction between a polyol group and an isocyanate group.
Learning how to apply polyurethane can give wood furniture and flooring a glossy, smooth finish while improving its durability. Read on for steps on how to apply polyurethane to furniture, plus tips for getting professional results. The two basic types of polyurethane are oil-based and water-based. Both have different pros and cons.
