2. Introduction
Diphenylmethane diisocyanate (MDI) is a member of the diisocyanate family associated with polyurethane chemistry. The term polyurethane applies to a large number of polymers formed through the polyaddition of polyfunctional isocyanates and isocyanate-reactive ...
3. MDI Products
MDI Production Process In the MDI process, aniline is condensed with formaldehyde to produce methylenedianiline (MDA), and MDA is reacted with phosgene to form MDI. The flexibility of the BASF process makes it possible to control and modify the properties of ...
4. Health Considerations
Acute Hazards MDI and products containing unreacted MDI are potentially hazardous materials. Therefore, a thorough knowledge of potential dangers, with strict adherence to recommended safety practices, is essential before MDI products are handled, stored, or ...
5. Safe Handling of MDI Products
MDI and products containing MDI are reactive and potentially hazardous chemicals. MDI should only be handled by knowledgeable and well-trained personnel who thoroughly understand the hazards associated with the transportation, storage, and use of the chemical....
6. Shipment of MDI
Although MDI is a hazardous material in terms of reactivity and toxicity, it can be transported and handled safely provided that appropriate precautions are observed. Regulations The shipment of MDI and MDI-containing products are subject to strict regulatio...
7. Storage
Storage and Handling Considerations A thorough knowledge of the chemical and physical properties of MDI, as well as all federal and local regulations and building codes, is necessary for the safe handling and storage of MDI products. When designing storage s...
8. Emergency Procedures
Guidelines for Dealing with MDI Product Incidents All incidents are unique so it is not possible to write guidelines to deal with every circumstance. Each incident must be assessed from the information available. All people involved with the handling or tran...
9. Environmental Considerations
The following recommendations should be interpreted in light of existing and future legislation. The disposal of liquid MDI wastes and used containers may be regulated by local, state, provincial, and federal agencies. Disposal of Waste MDI Products MDI prod...
