Product Description

Halogen-Free Ammonium Polyphosphate Flame Retardant With Low Water-Solubility


TF-201 is Ammonium polyphosphate phase II, the polymerization is over 1500, produced by a special method. TF-201 is almost insoluble in water and completely insoluble in organic solvents.


Expansion type fire-retardant coating based on polymer base material, and foaming agent, the dehydration into carbon catalyst, carbonation agents such as fire-retardant components, the coating formed in the expandable flame and high-temperature carbonization is compact and uniform of the honeycomb or spongy carbon foam layer, the bubbles is the original film thickness is several ten times or even hundreds of times, can well isolated from oxygen and heat conduction and coating a thin, is conducive to meet the requirements of decoration. From the point of view of the flame-retardant effect, decorative effect, and economic cost, the expansive fireproof coating is more widely used.




It acts as a flame retardant by the intumescence mechanism. When APP-II is exposed to fire or heat, it decomposes to polymeric phosphate acid and ammonia. The polyphosphoric acid reacts with hydroxyl groups to form a nonstable phosphate ester. Following dehydration of the phosphate ester, a carbon foam is built upon the surface and acts as an insulation layer.


It's widely used in coating, painting, adhesives, sealants, plastic masterbatch, and rubber.
