Numéro CAS

CAS 53317-61-6 — Polyuréthane prépolymère à base d'isocyanate de 4,4'-méthylènediphénylène (MDI) modifié.

Desmodur L75 is a polymeric methylene diphenyl diisocyanate (pMDI) used primarily in the production of rigid and flexible polyurethane foams, adhesives, and coatings. It serves as a key reactive component for cross-linking and enhancing mechanical properties in these applications. This isocyanate-based chemical is classified under CAS 53317-61-6, requires ambient storage, and carries a **Danger** signal word due to its hazardous nature. Molekula supplies Desmodur L75 from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
