PU Flame Retardant Ammonium Polyphosphate For RPUF Class B2 Used On Insulation Board And Thermal Insulation Pipe Sleeve
Ammonium Polyphosphate is a halogen free flame retardant , which can be used for rigid polyurethane foam instead of TCPP , TCEP .
On June 12 2020, Japan's Ministry of Finance officially announced that it would temporarily impose anti-dumping duties on phosphorous flame retardant TCPP from China , which is used in building insulation materials , and raise the duties on products related to the tariff to 37.2% in the next four months .
TCPP is a liquid organic phosphorous flame retardant , suitable for flexible and rigid PU foam.
Ammonium Polyphosphate (APP) is inorganic phosphorous flame retardant , suitable for rigid PU foam.
Ammonium polyphosphate (TF-501) is solid composite halogen-free phosphorus-nitrogen containing intumescent flame retardant, it acts both in the condensed phase and the gas phase.
Technical Data Sheet / Specification :
