Fine White Powder	≥31.0-32.0	14.0-15.0	5.5-7.0	≤0.25	≥275	About 1.9	100	About 0.5	About 0.5

2) Application in Expand Dope

(1) For the little water solubility, APP is specially applicable for the acid base of the expand dope which meets Class DIN4102 of fire fighting on the steel structure, also can be applied on wood or plastic as expand dope .

（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.
