Cresyl diphenyl phosphate
Description
Cresyl diphenyl phosphate (CAS 26444-49-5), also known as CDP or by the trade name Disflamoll DPK, is an organophosphate ester used across industrial manufacturing as a combined flame retardant and plasticizer.
Its multifunctional profile allows formulators to reduce flammability while maintaining or improving material flexibility. This addresses two performance requirements with a single additive for various polymer systems.
In PVC and engineering polymer compounds, CDP imparts both plasticization and flame retardancy, reducing the need for separate additive packages. This efficiency is highly valued in large-scale chemical manufacturing.
Hydraulic fluids and fire-resistant lubricants for aerospace and industrial equipment rely on CDP to meet demanding ignition-resistance specifications. It ensures safety in high-pressure and high-temperature environments.
The electronics sector uses it in wire and cable insulation compounds where UL flame ratings and flexibility must be achieved simultaneously. This makes it a critical component for modern electrical infrastructure.
In construction materials, including flooring and wall coverings, CDP supports compliance with fire safety standards without compromising processability. It integrates seamlessly into existing production workflows.
Cresyl diphenyl phosphate is supplied as a clear to pale yellow liquid. It is available in technical grade, which is the standard commercial form for industrial and polymer applications across the global market.
Bulk liquid supply in drums and ISO containers is the typical packaging format for industrial procurement volumes. This ensures reliable logistics and handling for high-capacity manufacturing facilities.
