2. Application in Expand Dope

(1) Ammonium polyphosphate is an excellent choice for top-tier fire-retardant coatings, fiberglass, and engineering plastics. It's highly suitable for use with materials such as PE, PP, PU, polyester, and nylon, providing superior flame resistance.
(2) When incorporated into adhesives and sealing agents at a concentration of 15-20%, ammonium polyphosphate exhibits remarkable fire resistance, ensuring enhanced safety and reliability.
(3) In polyurethane applications, APP serves as an ideal halogen-free flame-retardant additive, effectively preventing combustion and enhancing safety.
(4) It is perfect for use in fiber-based materials, including paper and wood products, as well as in hot-curing resins like epoxy and unsaturated resins, offering versatile fire-retardant capabilities.
