Product description
Ammonium polyphosphate flame retardant is a phosphorus-nitrogen based intumescent flame retardant that complies with EU environmental protection requirements. The flame retardant has stable performance, does not deteriorate after long-term storage, and is easy to transport and store. It has a neutral pH value, high P-N content, no chemical reaction with other flame retardants, good synergistic effect, and affordable price.
Flame retardant mechanism
The flame retardant is heated and dehydrated under high temperature conditions to generate polyphosphoric acid or metaphosphoric acid. It can be used as a strong dehydrating agent to dehydrate the carbon-forming substances in the flame retardant system to form a simple carbon layer. The non-flammable gas generated by the gas source is It forms an expanded carbon layer to isolate air and fire sources, thereby achieving efficient flame retardancy of the product.
