Tcpp Flame Retardant For Pu Rigid Foam

Tcpp is a chlorinated phosphate ester commonly used in both rigid polyurethane (pur) and poyisocyanurate (pir) foams, which can meet the gb8624-2012-b1&b2 fire standard. its obvious feature is having little effect on mechanical properties by adding tcpp, and extending pot life. technical specification appearance: colorless to pale yellow transparent liquid phosphorus content (%wt): 9.4 chlorine content (%wt): 32.5 acidity (mgkoh/g): ?0.10 water content (%wt): ?0.10 viscosity (mpa.s@25?): 65
