Ammonium Polyphosphate Introduction
Ammonium Polyphosate can be used in top-grade fire-retardant coating, fiberglass and engineering plastic, such as PE, PP, PU, polyester and nylon.
Ammonium polyphosphate (APP) II is one kind of non halogen flame retardant. It has extensive possibilities in fire prevention.
1.The advantage of our ammonium polyphosphate flame retardants:
(1)High degree of polymerization up to 1300, excellent performance of fire protection in intumescent systems, has more wide range of application than low polymerization APP.
(2)Initial decomposition temperature 280 degree Celsius, action time earlier than other common ammonium polyphosphate
(3)Low water solubility, high polymerizaiton and intial decompostion temperature make our ammonium polyphosphate good compatibility.
2.Application in Expand Dope

2.Application in Expand Dope
(1) With 15-20% APP in the adhesive and sealing agent, the good firing resistance is shown.
(2) For PU, APP is a very suitable preventing form buring dope without halogen.
(3) It is also applicated in hot solidifying resin of epoxy resin or unsaturated resin, etc.
