Benzene, 1,1'-metilenbis[4-isocianato-

Descrizione:

La sostanza chimica nota come Benzene, 1,1'-metilenbis[4-isocianato-, comunemente chiamata MDI (Diisocianato di Metilene Difenilico), è un isocianato aromatico utilizzato principalmente nella produzione di schiume e rivestimenti in poliuretano. È caratterizzata dalla sua alta reattività grazie alla presenza di gruppi funzionali isocianato, che reagiscono facilmente con composti contenenti atomi di idrogeno attivi, come alcoli e ammine. L'MDI è tipicamente un liquido viscoso o solido a temperatura ambiente, con un odore aromatico distintivo. È insolubile in acqua ma solubile in solventi organici come acetone e toluene. L'MDI è noto per la sua eccellente stabilità termica e proprietà meccaniche, rendendolo adatto per varie applicazioni industriali, inclusi materiali isolanti ed elastomeri. Tuttavia, è anche associato a rischi per la salute, poiché l'esposizione può portare a problemi respiratori e sensibilizzazione della pelle, richiedendo un'adeguata manipolazione e precauzioni di sicurezza negli ambienti industriali.

Methylenedi-p-phenyl diisocyanate

CAS: 101-68-8

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.
