What is Cresyl diphenyl phosphate?
Cresyl diphenyl phosphate (CAS 26444-49-5), also known as CDP or by the trade name Disflamoll DPK, is an organophosphate ester used as a combined flame retardant and plasticizer.
Where is Cresyl diphenyl phosphate used?
- PVC and engineering polymer compounds: plasticization and flame retardancy, reducing the need for separate additive packages
- Hydraulic fluids and fire-resistant lubricants for aerospace and industrial equipment: ignition-resistance specifications
- Electronics: wire and cable insulation compounds with UL flame ratings and flexibility
- Construction materials such as flooring and wall coverings support fire safety compliance without compromising processability.
Commercial specifications
- Bulk liquid supply in drums and ISO containers
