Applications
- Rigid Insulation Panels — Main raw material for PIR/PUR rigid foam insulation panels used in GCC construction projects
- Sandwich Panels — Used with polyol and blowing agent to produce sandwich panels for industrial buildings and cold rooms
- Spray Foam — Combined with polyol system in two-component spray foam for on-site insulation and air sealing
- Wood Binders — Used as a binder (PMDI) in particle board and MDF production — provides excellent bond strength
- Refrigeration — Insulation foam for refrigerators, freezers, and cold chain logistics equipment
- Refrigerator and cold room insulation
- Structural insulated panels (SIPs)
- PU sealant and adhesive systems
Yes. Polymeric MDI must be stored in sealed containers away from moisture and water. Contact with water or humidity causes irreversible reaction. Recommended storage temperature is 15–30°C. Shelf life is typically 6 months from the date of manufacture when stored correctly. Refer to the full SDS.
