Product Description

Excellent Grade Ammonium Polyphosphate (APP) for Fire Retardant Coatings


1. Application in Expand Dope

(1) ammonium polyphosphate can be used in top-grade fire-retardant coating, fiberglass and engineering plastic, such as PE, PP, PU, polyester and nylon.
(2) With 15-20% APP in the adhesive and sealing agent, the good firing resistance is shown.
(3) For PU, APPis a very suitable preventing form buring dope without halogen.
(4) It applies for fiber basic materials (like paper, wood products), hot solidifying resin of epoxy resin or unsaturated resin, etc.
