Tris Phosphate

Tris Phosphate

TCPP, or Tris(1-chloro-2-propyl) Phosphate, is a flame retardant commonly used in flexible polyurethane foams, textiles, adhesives, coatings, and synthetic rubber. It acts by releasing phosphorus compounds that inhibit the spread of fire. TCPP is a colorless to pale yellow liquid with a characteristic odor, and its use is subject to regulations due to environmental and health concerns.
