| Hazard Information | Back Directory | [Chemical Properties]
liquid | [General Description]
Dark-brown liquid with a weak odor. Sinks in water. | [Air & Water Reactions]
Reacts with water slowly forming heavy scum and liberating carbon dioxide gas. Dangerous pressure can build up if container is sealed. | [Reactivity Profile]
Polymethylene polyphenyl polyisocyanate reacts with water slowly forming heavy scum and liberating carbon dioxide gas. Dangerous pressure can build up if container is sealed. Base-catalysed reactions of isocyanates with alcohols should be carried out in inert solvents. Such reactions in the absence of solvents often occur with explosive violence [Wischmeyer 1969]. | [Health Hazard]
Inhalation causes breathlessness, chest discomfort, and reduced pulmonary function; wheezing, cough, and sputum may also occur. Contact with liquid irritates eyes and skin. Ingestion causes irritation of mouth and stomach. | [Fire Hazard]
Behavior in Fire: Containers may explode. | [Hazard]
Questionable carcinogen. | [Description]
Polymethylene polyphenyl polyisocyanate is a chain extender and a cross-linker that is used in the formation of a polyurethane system by forming amide linkages (?NCO). | [Uses]
Poly[methylene(polyp?henyl Isocyanate)?] is an engineering polymer used in the synthesis of highly resiliant polyurethane foams with flame retardancy.Environmental toxin on US EPA Toxic Release Inventory list (TRI) list. | [Application]
Polymethylene polyphenyl polyisocyanate can be used as a cross-linker to DNA and CTMA based films for the fabrication of biomaterials for organic electronic devices. It can be used in the formation of polyurethane based materials for non-linear optical applications. |
