About Cresyl Diphenyl Phosphate

Diphenyl cresyl phosphate (CDPP), is a high-efficiency liquid organophosphate ester. Within the Flame Retardants, Industrial Chemicals, and Polymer Additive hierarchies, cdp valued as a versatile "low-smoke" flame retardant and plasticiser. Unlike solid phosphates, CDP’s liquid state at room temperature allows for seam...

Flame Retardants: Flexible PVC & PU Foams

Flexible PVC used in wire and cable insulation. Excellent flame-extinguishing properties in both the condensed and vapor phases. Utilized in Polyurethane (PU) foams to achieve stringent fire safety ratings while maintaining the foam's soft tactile properties

Polymer Processing: Oil-Resistant Plasticizer

In synthetic rubbers (like NBR and SBR), CDP acts as a plasticizer that significantly improves the material's resistance to oils and fuels. High solvency ensures rapid fusion during the extrusion of specialised hoses and gaskets

Industrial Fluids: Lubricant & Hydraulic Additive

Anti-wear (AW) and extreme pressure (EP) additive in high-temperature lubricants and fire-resistant hydraulic fluids. Protective phosphorus-rich layer on moving metal parts

Detail 1

Stable under normal storage conditions

Detail 2

Low volatility ensures minimal loss during high-temperature processing (e.g., PVC calendering)

Detail 3

Store in a cool, dry, well-ventilated area. Keep containers tightly sealed

Detail 4

Recommended storage is 15° C to 30°C

Detail 5

Shipping can be Available in 200kg drums, 1000kg IBCs, or ISO tanks for global bulk transport
