APP is a kind of phosphorus and nitrogen series, non-halogen, environmentally friendly flame

retardant, commonly used in the preparation of fireproof coatings.The flame retardant mechanism

of APP is to decompose at high temperature to produce phosphoric acid and ammonia,

phosphoric acid can catalyze the carbonization reaction to form a charcoal layer, preventing the

transfer of heat and oxygen, and ammonia can dilute the oxygen in the air to inhibit the flame

combustion.

It has excellent water resistance, aging resistance and good thermal stability. Its flame retardant

properties are excellent and long-lasting, and it has obvious synergistic effect when compounded

with other flame retardants. It fully complies with EU RoHS and REACH standards and reaches

UL94-V0 level.
