Reaction with water to form Carbon Dioxide [Merck 11th ed. rates but will be much higher in eastern and central Europe, Inhalé à forte dose par la souris ou le rat, il produit une hypersalivation, une léthargie puis la mort. TDI is classified as “very toxic”. Pre-Registration process . flexibility, strength, abrasion resistance, shock absorbency 2,4-Toluene Diisocyanate CAS RN: 584-84-9 Disposal Methods. The majority of flexible foams are produced by the slabstock D.C. Allport et D.S. manufactured from flexible PU foams. where it gradually expands into a large bun of foam. TOLUENE-2,6-DIISOCYANATE reacts violently with amines, alcohols, bases and warm water, causing fire and explosion hazards. foaming process, in which the mixture of polyurethane raw Unit. With most of TDI’s output going into the furniture and Despite their relatively Association of Automobile Manufacturers. Demand in western Europe will also grow more slowly at GDP Le TDI ne semble pas avoir d'effet sur la fertilité. It also has numbers of commercial applications. Toluene diisocyanate (TDI) has been classified as carcinogenic in animals on the basis of gavage administration studies, but no conclusions are available on inhalation exposure. These Toluene Diisocyanate (TDI) CAS:584-84-9. incorporated in a single process. There is also a trend towards using bio-based Toluene diisocyanate (TDI) exists as two isomers; 2,4-TDI and 2,6-TDI. In this study, we optimized our mouse model of chemical-induced asthma in the C57Bl/6 mice strain using the model agent TDI. Another important foaming technique is the moulded foam 1. Besides this TDI or Toluene Diisocyanate is also used to boost octane in gasoline. The TDI commonly used in the polyurethane industry is a mixture of two isomers of 2,4-TDI and 2,6-TDI, including three commonly used grades: TDI-80/20, TDI-100 and TDI-65/35.
