TCPP IS A CHLORINATED PHOSPHATE ESTER COMMONLY USED IN BOTH RIGID POLYURETHANE FOAMS (PUR AND PIR) AND IN FLEXIBLE POLYURETHANE FOAMS.
TCPP, SOMETIMES REFERRED TO AS TMCP, IS AN FLAME RETARDANT ADDITIVE THAT CAN BE COMBINED IN EITHER SIDE OF A TWO COMPONENT URETHANE PACKAGE TO ACHIEVE LONG TERM STABILITY.
IN RIGID FOAM APPLICATION, TCPP IS WIDELY USED IN FLAME RETARDANT PACKAGES TO HELP FORMULATORS PASS FIRE SAFETY CODES SUCH AS THE DIN 4102 (B1/B2), EN 13823 (SBI, B), GB/T 8626-88 (B1/B2), ASTM E84-00.
IN FLEXIBLE FOAM APPLICATION, THE COMBINATION OF TCPP AND MELAMINE CAN REACH THE BS 5852 CRIB 5 STANDARD

Flame Retardant
