Description
PMDI
Polymeric Methylene diphenyl Di-Isocyanate Crude (Low Functionality)
Product Description
The current manufacturing technology of most isocyanates is based on the phosgenation of primary amines.
Applications:
Polymeric MDI is commonly used to manufacture:
- Rigid foams- used to produce sandwich panels and polyurethane wood.
- Flexible foams – used for the fabrication of prepolymers for bedding, furniture, automotive seating, flexible packaging and carpet underlay; this is the largest market application for Polymeric MDI
- “Foamed-in-place” polyurethane plastics – ranging from soft and sponge-like to hard and porous for use in furniture, packaging, insulation and boat building
- Polyurethane coatings – used on leather, wire, tank linings and masonry
- Rigid, “pour-in-place” foams – for use in appliances, and, in smaller amounts, packaging
- Cast elastomers – for production of articles such as roller blade wheels

Handling and storage conditions
Use only with adequate ventilation. Do not eat, drink, or smoke in working area. Never use welding/cutting torch near storage containers, even if empty, because even residual product can ignite explosively. Product must be stored at 20°C to 40°C.
Storage stability: The best time is 6 month and it can be extended to 12 month.
Packing details
