Product Details

Products Description of Tolylene-2,4-diisocyanate CAS#584-84-9

Toluene diisocyanate (TDI), (OCN)2C6H3CH3, is a water-white to pale-yellow liquid with a sharp, pungent odor. It reacts with water to launch carbon dioxide. The specific gravity is 1.22, which is heavier than water. TDI is toxic with the aid of potential of inhalation and ingestion, and is a sturdy irritant to pores and pores and skin and different tissue, usually the eyes. The TLV is 0.005 ppm in air, and the IDLH is 10 ppm.

Product Application of  Tolylene-2,4-diisocyanate CAS#584-84-9

Toluene-2,4-diisocyanate is one of the mostextensively used isocyanates. It is usedin the manufacturing of inflexible and flexibleurethane foams, elastomers, and coatings. Inaddition to its use as a pure compound, itis commercially reachable as a combination of2,4- and 2,6-isomers (80 : 20% and sixty five : 35%ratios, respectively).Occupational allergies is the most important purpose of work-related respiratory disorder in the industrial world. Toluene-2,4-diisocyanate (TDI) is one of the most frequent respiratory sensitizers main to occupational asthma.
