Product Description

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 :

Specification TF-501
Appearance Gray powder
P2O5 content (w/w) ≥47%
N content (w/w) ≥8%
pH value (10% aqueous suspension, at 25ºC) 6.5-7.5
Moisture (w/w) ≤0.5%

 

Characteristics :
1. Gray powder, expands when heated, efficient in smoke suppression.

2. Excellent water resistance, not easy to precipitate, high flame retardant efficiency.
3. Halogen-free and none heavy metal ions. pH value is neutral, safe and stable during production and use, good compatibleness, not to react with other flame retardant and auxiliary.
