Aromatic Isocyanates Are Mostly Used To Make Polyurethane Foam
Isocyanates are organic compounds that have the -N=C=O group attached to them. A di-isocyanate group is formed when two of these groups are linked to a chemical. Aromatic isocyanates and aliphatic isocyanates are the two main forms of isocyanate compounds. Aromatic isocyanates are mostly formed by directly attaching an NCO group to aromatic rings. Aromatic isocyanates are used to make polyurethane foam,

Organic molecules with the –N=C=O group are known as isocyanates. When two of these functional groups are connected to a molecule, the group is referred to as a di-isocyanate. Aromatic and aliphatic isocyanate compounds are the two types of isocyanate compounds. Aromatic Isocyanates are formed when an NCO group is directly attached to aromatic rings.Aromatic isocyanates are mostly used to make polyurethane foam, which is made by combining aromatic isocyanates with polyols in the presence of a catalyst. 

Aromatic isocyanates are commonly used to make flexible and rigid foam, elastomers, and protective coatings, among other things. In nature, these chemicals are highly reactive and poisonous. Because of their toxicity, particular precautions are necessary in their handling and production.Tolune, benezene, and aniline are some of the raw ingredients utilised in the manufacturing of aromatic Isocyanates. Toluenediisocyanate (TDI) and Methylenediphenyl diisocyanate (MDI) are two aromatic compounds that are commonly used to make rigid foam in the building industry.
