Description
Tri(2-chloroethyl) phosphate (TCEP, CAS 115-96-8) is an organophosphate flame retardant and plasticizer traded under names including Celluflex CEF, Niax Flame Retardant 3CF, and AURORA KA-1645. It carries no E-code designation and is classified under HS code 29199000. No Ph.Eur. or FCC monograph applies to this substance.
In flexible polyurethane foams used in automotive seating and building insulation, TCEP interrupts combustion by releasing chlorine radicals that quench flame propagation in the gas phase. It also functions as a reactive plasticizer in coatings and adhesives, reducing flammability while maintaining film flexibility. Secondary antimicrobial activity has been documented in textile and leather processing applications.
TCEP is supplied as a neat liquid and is subject to REACH registration obligations within the EU; procurement teams should verify current SVHC status and any applicable authorization requirements before sourcing. Packaging typically follows standard bulk liquid formats including drums and IBCs.
