2,2′-MDI

Description:

2,2′-MDI, or 2,2′-methylenediphenyl diisocyanate, is an aromatic diisocyanate commonly used in the production of polyurethanes. It is characterized by its two isocyanate functional groups, which enable it to react with polyols to form polyurethane polymers. This compound typically appears as a pale yellow to brownish liquid or solid, depending on its temperature and purity. 2,2′-MDI is known for its high reactivity, particularly with moisture, which can lead to the formation of urea linkages. It has a relatively high boiling point and low volatility, making it suitable for various industrial applications, including coatings, adhesives, and elastomers. However, it is also associated with potential health hazards, including respiratory irritation and sensitization, necessitating the use of appropriate safety measures during handling. Its chemical stability and reactivity make it a valuable component in the production of durable materials, contributing to the versatility of polyurethane products in numerous applications.
