ICPP (Tris 1-Chloro-2-Propyl Phosphate) is an organophosphate compound with the chemical formula C₉H₁₉Cl₃O₄P. It is used as a flame retardant in many industrial and commercial products to provide non-flammability properties.

ICPP is primarily used as a flame retardant to enhance the fire resistance of various materials, including polyurethane foams, plastics, resins, adhesives, and coatings. By preventing materials from catching fire, it increases fire safety.

ICPP is a preferred flame retardant due to its chemical properties and ability to provide non-flammability. However, proper handling and processing of the chemical are crucial. It is important to follow safe use instructions and be aware of potential risks and health effects associated with its use.
