Flame Retardant TDCPP for Polyester (Tris Chloroalkyl Phosphate)
CAS Number: 13674-87-8
Tris(1,3-dichloro-2-propyl) phosphate (TDCPP) is a halogen-phosphorus synergistic flame retardant for polyester and polyester-blend fabrics. Applied via padding or back-coating, it provides effective flame retardancy by releasing HCl and phosphorus-based radicals in the gas phase during combustion. Meets EN 13501-1 (Class B-s2), MVSS 302, and various upholstery FR standards.
