Toluene 2,6-diisocyanate

Description:
Toluene 2,6-diisocyanate (TDI), with the CAS number 91-08-7, is an aromatic isocyanate primarily used in the production of flexible polyurethane foams. It is characterized by its low viscosity and volatility, which facilitate its application in various industrial processes. TDI is a colorless to pale yellow liquid with a distinct odor, and it is known for its reactivity with nucleophiles, particularly amines and alcohols, leading to the formation of polyurethanes. The compound is classified as hazardous; it can cause respiratory irritation and sensitization upon exposure, necessitating the use of appropriate safety measures during handling. TDI is also subject to environmental regulations due to its potential toxicity and impact on human health. Its applications extend beyond foams to coatings, adhesives, and elastomers, making it a versatile chemical in the polymer industry. Proper storage and handling practices are essential to mitigate risks associated with its use.
