Bookmark or Share- Introduction to Polyurethane Chemistry - ACS PublicationsPolyurethanes 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. Oto Bayer and partners (1).
- Polyurethane - WikipediaPolyurethane ( / ˌpɒliˈjʊərəˌθeɪn, - jʊəˈrɛθeɪn /; [1] often abbreviated PUR and PU) refers to a class of polymers composed of organic units joined by carbamate (urethane) links. In contrast to other common polymers such as polyethylene and polystyrene, polyurethane is produced from a wide range of starting materials.
- What Is Urethane? - How Polyurethane Is Used Around The World - TPCWhat is Urethane? Stated by urethane manufacturers, urethane by itself is a crystalline compound that is considered an ester of carbonic acid, which means it has been heated with alcohol with an acid catalyst. The urethane chemical formula is C3 H7 NO2.
- Ethyl carbamate - WikipediaThese esters are white, crystalline solids at room temperature. Except for the phenyl carbamate, they sublime at moderate temperatures; methyl carbamate sublimes at room temperatures. The first two and ethyl carbamate are very soluble in water, benzene, and ether.
- Urethane | NH2COOC2H5 | CID 5641 - PubChemDescription. Urethane appears as odorless colorless crystals or white powder. Sublimes readily at 217 °F and 54 mmHg. Cooling saline taste. CAMEO Chemicals. Urethane is a carbamate ester obtained by the formal condensation of ethanol with carbamic acid. It has been found in alcoholic beverages. It has a role as a fungal metabolite and a mutagen.
