QHA TCPP(TOPP) Product Datasheet
1. Description
QHA TCPP (TOPP) is a high-efficiency halogenated phosphate ester flame retardant, chemical name Tris(2-chloroisopropyl) phosphate, CAS No. 13674-84-5. It appears as colorless to pale yellow transparent liquid with low viscosity, good compatibility, excellent hydrolysis resistance and thermal stability. It provides both phosphorus–chlorine synergistic flame retardancy and plasticizing effect, widely used in many polymer systems to improve flame retardancy, processing performance and low-temperature flexibility.
