Polymeric MDI (Crude MDI) | CAS 9016-87-9 | Supplier UAE & GCC

Polymeric MDI (Methylene Diphenyl Diisocyanate, Crude MDI, CAS 9016-87-9) is a dark brown, viscous liquid isocyanate with a functionality of 2.7–3.0. It is the primary raw material for rigid polyurethane foam production — used in building insulation panels, sandwich panels, refrigeration insulation, and spray foam. Polymeric MDI offers higher functionality than pure MDI (MDI 100), producing more crosslinked, rigid foam structures. Raykem supplies Polymeric MDI across the UAE, Saudi Arabia, and the GCC with full COA, SDS, and GHS-compliant documentation.

Frequently Asked Questions

What is the difference between Polymeric MDI and Pure MDI (MDI 100)?
Polymeric MDI (Crude MDI) has functionality 2.7–3.0 and is primarily used for rigid foam where high crosslinking is desired. Pure MDI (MDI 100, 4,4'-MDI) has functionality ~2 and is used for elastomers, coatings, adhesives, and RIM applications requiring better processing characteristics.
What NCO content does Raykem supply for Polymeric MDI?
Raykem supplies Polymeric MDI with NCO content of 30.5–32.5% and viscosity of 150–250 mPas at 25°C, which is the standard industrial specification. COA for each batch confirms exact NCO content and viscosity. Contact us if a non-standard specification is required.
Does Polymeric MDI require special storage conditions?
