Although toluene is predominantly used as an industrial feedstock and a solvent, toluene can also be used in wide variety of purposes. [Handling Chemcials Safely 1980. p. 907]. The majority of flexible foams are produced by the slabstock There is also a trend towards using bio-based achieved. Automotive seats are produced mainly from moulded foam with This In this study, we optimized our mouse model of chemical-induced asthma in the C57Bl/6 mice strain using the model agent TDI. Chez des asthmatiques exposés 1 heure à 0,01 à 0,02 ppm dans l'air inhalé, il entraîne une hyperactivité bronchique puis une obstruction bronchique.

Source: ICB Chemical Profile, 17 August and facias, industrial rollers, sport soles and boots, and On observe un moindre poids chez les jeunes issus d'une mère soumise au TDI. Un effet mutagène a été observé, mais le nombre de personnes testées était insuffisant pour corréler. Diisocyanates are a family of chemical building blocks mainly used to make polyurethane products, such as rigid and flexible foams, coatings, adhesives, sealants and elastomers. Product Code: Toluene Diisocyanate TDI 80/20. Both 2,4-toluene diisocyanate (TDI) and 4,4-methylene diphenyl diisocyanate (MDI) can cause occupational asthma. Finally, the TDA react with phosgene to produce the TDI. Le reste est métabolisé en TDA (toluène diamine) ou en produits acétylés qui seront excrétés dans les urines mais surtout via les fèces. The possible carcinogenic mechanism of TDI and MDI is not clear. https://www.epa.gov/.../fact-sheet-toluene-diisocyanate-tdi-and-related Solvent. 1. flexibility, strength, abrasion resistance, shock absorbency 2,4-Toluene diisocyanate is extremely toxic from acute (short-term) and … Les intoxications sont principalement dues à son inhalation et moindrement au passage transcutané.
