Product Description

High Polymerization Degree Ammonium Polyphosphate Flame Retardants For Intumescent Fireproof Coating

 

FR002 APP ammonium polyphosphate is Nitrogen-phosphorus inorganic flame retardants, it is a kind of crystal type Ⅱ ammonium polyphosphate, FR002 APP ammonium polyphosphate has high polymerization degree, but without encapsulated and activated. It has high content of phosphorus and nitrogen, excellent thermal stability, near-neutral and non-toxic smoke property. With gas source and carbon source, it takes effect by char formation and intumescent mechanism. FR002 ammonium polyphosphate Nitrogen-phosphorus inorganic flame retardants iswidely used for intumescent fireproof coating.

Characteristics:

  • Good thermal stability;
  • Low viscosity and good dispersity;
  • Low water solubility, good anti-migration and anti-precipitation;
  • High polymerization degree (n≥1000), narrow molecular weight distribution, less content of low
  • Polymerization substance;
  • High purity of type Ⅱ structure;
  • Excellent particle size distribution.

 

Application:

Meetting the requirements of different applications. And it is highly recommended to intumescent coating.

 

FR002 has very low water solubility and is particularly suitable as an acid source for intumescent fireproof coatings. Other important components of intumescent fireproof coatings include binders (such as acrylic), carbon sources (such as pentaerythritol), gas sources (such as melamine), and so on. After being exposed to flame, the intumescent fire retardant coating will form a dense carbon layer on the surface, effectively blocking the temperature rise of the substrate. FR002 applied to intumescent fireproof coatings has the following effects:

 

Wood or plastic EN 13501 -1 Class B standard
Steel structure materials EN, DIN, BS, ASTM and GB fire protection standards
