  • What is The Difference Between MDI and TDI?

    2023-07-10

    Introduction of TDIThe chemical formula of toluene diisocyanate (TDI), an organic substance, is CH3C6H3(NCO)2. Commercially significant isomers include 2,4-TDI (CAS: 584-84-9) and 2,6-TDI (CAS: 91-08-7), two of the six potential isomers. Although 2,4-TDI is synthesized in its pure form, it is freque Read More
  • The Difference Between MDI and TDI

    2023-07-10

    Diisocyanates come in two main varieties: MDI and TDI. These are helpful in the creation of polyurethane. Diisocyanates come in two main categories: aromatic diisocyanates and aliphatic diisocyanates. Aromatic diisocyanates come in the shapes of MDI and TDI.What is MDI?Methylenediphenyl diisocyanate Read More
  • The Health Hazard And Risk of MDI

    2023-07-06

    An aromatic diisocyanate is methylene diphenyl diisocyanate (MDI). There are three common isomers: 2,2′-MDI, 2,4′-MDI, and 4,4′-MDI. These are distinguished by the locations of the isocyanate groups around the rings. The most common isomer, commonly known as 4,4′-diphenylmethane diisocyanate, is the Read More
