Polyurethane - Wikipedia Unlike polyethylene and polystyrene, polyurethanes can be produced from a wide range of starting materials, resulting in various polymers within the same group This chemical variety produces polyurethanes with different chemical structures leading to many different applications
All About Polyurethane - This Old House Polyurethane provides a durable, protective finish for floors or furniture in your home In this guide, we discuss the various types of polyurethane, when to use each one, and how to apply the coating to get a beautiful result
What is polyurethane? - Polyurethanes Polyurethanes were invented back in the 1930s by Professor Dr Otto Bayer (1902-1982) There are various types of polyurethanes, which look and feel very different from each other They are used in a diversity of products, from coatings and adhesives to shoe soles, mattresses and foam insulation
Polyurethane: What It Is, History, and How It’s Made | Xometry 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
Introduction to Polyurethane Chemistry - ACS Publications Polyurethanes are an immensely versatile class of polymers used in insulators, foams, elastomers, synthetic skins, coatings, adhesives, and so forth Polyurethane was first developed through basic diisocyanate polyaddition reactions by Dr Otto Bayer and partners (1)
What is Polyurethane? - BYJUS What is Polyurethane? Polyurethane, often abbreviated to PU or PUR, is an organic polymer that features many organic units linked via urethane molecules Most polyurethanes do not melt upon heating and can, therefore, be classified as thermosetting polymers
