MDI and TDI are polymer building blocks with a wide range of applications in industry. Both are used in large quantities and can be found in a wide variety of industries and applications. As their use will often involve large numbers of workers they are also subject to stringent health and safety regulations. This book covers all the important topics concerning MDI and TDI and provides comprehensive coverage on the health and environmental science associated with these. Considering the risk management of both substances this is the first book to offer comprehensive discussion of health and environmental issues and includes _ insights from academic, regulatory, and industrial experts _ numerous photographs, spectra, tables, and graphs _ additional information on physical properties and analysis _ Considers the risk management of these two diisocyanates Addressing their use throughout industry this title presents an essential source of information for occupational physicians, industrial hygiene professionals, polyurethane producers, environmental scientists, chemical analysts and regulators.Hinweis: Dieser Artikel kann nur an eine deutsche Lieferadresse ausgeliefert werden.
