Chlorine (theoretical): 32.5%
Phosphorus (theoretical): 9.5%
Tri content, %: 50 to 85%
Acid value (mg KOH/g): ≤0.07
Moisture: ≤0.07%
Color (APHA): ≤50
Viscosity (25°C, mPa.s): 65 to 70
Specific gravity: 1.27 to 1.31
Primary Chemistry:
Phosphorus & Chlorine blend
Low hydrolytic stability of flame retardants in rigid and flexible PU foams
High loading rate of phosphorus-based flame retardants
Urethane foam
Flame retardants are used as reactive chemical additives in combustible polymers to prevent, delay, or slow the growth of a fire.
