Benzene, 1,1'-methylenebis[4-isocyanato-

Description:
The chemical substance known as Benzene, 1,1'-methylenebis[4-isocyanato-], commonly referred to as MDI (Methylene Diphenyl Diisocyanate), is an aromatic isocyanate used primarily in the production of polyurethane foams and coatings. It is characterized by its high reactivity due to the presence of isocyanate functional groups, which readily react with compounds containing active hydrogen atoms, such as alcohols and amines. MDI is typically a viscous liquid or solid at room temperature, with a distinct aromatic odor. It is insoluble in water but soluble in organic solvents like acetone and toluene. MDI is known for its excellent thermal stability and mechanical properties, making it suitable for various industrial applications, including insulation materials and elastomers. However, it is also associated with health risks, as exposure can lead to respiratory issues and skin sensitization, necessitating proper handling and safety precautions in industrial settings.

  • Methylenedi-p-phenyl diisocyanate

    CAS:
    <p>Methylenedi-p-phenyl diisocyanate (MDI) is a glycol ether, which is a potent inducer of allergic reactions. It can be found in polyurethane foam insulation and in the production of diphenyl and diisocyanate. MDI has been shown to cause asthma, skin inflammation, and other respiratory problems. MDI is highly toxic to aquatic life and can cause long term effects on fish populations. The toxicity of MDI depends on the concentration and duration of exposure, as well as the species that it is administered to. High concentration exposure for a short period of time will result in death by respiratory failure or cardiac arrest. Longer exposure at lower concentrations may lead to liver, kidney, lung damage or cancerous tumor development.</p>
