Polymethylene polyphenyl polyisocyanate Chemical Properties,Usage,Production
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).
Chemical Properties
liquid
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.
Definition
A polymer of diphenylmethane-4,4′-diisocyanate.
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.
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].
Hazard
Questionable carcinogen.
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.
Safety Profile
Moderately toxic by ingestion. Mildly toxic by inhalation. Questionable carcinogen with experimental neoplastigenic data by implant route. When heated to decomposition it emits toxic fumes of NOx.
