Product Features
Appearance of APP flame retardant is a white powdery solid, with fine precision, white color and high degree of polymerization. It is almost insoluble in water, completely insoluble in organic solvents, non-hygroscopic and non-flammable. White fluid powder (standard blue light whiteness ≥94, average particle size 10um-55um) molecular formula is (NH4)n+2PnO3n+1
Product special 1. It has strong anti-hygroscopicity and can be widely used in fire and flame retardant under various conditions inside and outside the building.
2. The decomposition temperature is high, and it has good thermal stability under various natural conditions.
3. The PH value is close to neutral, and it has good compatibility with paint, rubber and other polymers and resins, and can obtain a uniform and good appearance.
4. Fine particle size, white color, good powder fluidity.
5. It can be used alone with other flame retardants.
