Usage

General Description

Methylene diisocyanate (MDI) is a versatile chemical compound used in the production of polyurethane foams, elastomers, and adhesives. MDI is a highly reactive chemical that is known for its strong and durable properties, making it an important component in a wide range of industrial products. However, exposure to MDI can pose serious health risks, including irritation to the skin, eyes, and respiratory system, as well as potential long-term effects on the respiratory and immune systems. As a result, strict safety measures and guidelines are in place to minimize the risks associated with handling and using MDI in industrial settings.
