Tris(1,3-dichloro-2-propyl) phosphate (TDCPP, also known as TDCIPP) is a highly effective halogen-phosphorus flame retardant and plasticizer for flexible polyurethane foam, achieving excellent FR ratings at moderate loadings through the synergistic action of chlorine and phosphorus. It exhibits lower volatility and migration compared to TCEP, making it more suitable for open-cell foam furniture and mattress applications. Note: TDCPP has been added to California's Proposition 65 list and is under evaluation in multiple jurisdictions; buyers should verify applicable regulations.

Technical Specifications

appearance	Colorless to pale yellow liquid
chlorine content (%)	48.5–49.5
flash point (COC, °C)	>230
phosphorus content (%)	7.2–7.5
density (20°C, g/cm³)	1.50–1.53
viscosity (25°C, mPa·s)	90–150

Applications

Flexible polyurethane foam for furniture, mattresses, and automotive seating FR
Semi-rigid polyurethane foam for automotive headrests and armrests
Rigid polyurethane foam insulation where chlorinated FR is acceptable
PVC plastisols and coatings requiring liquid halogen-phosphorus flame retardant
Carpet and textile back-coating applications in permitted jurisdictions

Key Features

Lower volatility and migration than TCEP provides longer-lasting FR performance in open-cell foam applications
High chlorine content (49%) with phosphorus synergism delivers maximum halogen-phosphorus FR efficiency
Good hydrolytic stability at ambient conditions prevents FR degradation in polyurethane foam over service life
