| Brief introduction: |
 |
| Crystalline phase Ⅱ ammonium polyphosphate is a kind of environment protection non-halogen flame-retardant cotaining N and P. It has high polymerization degree, good heat-stability and small hygroscopicity. It differs from the halogen flame-retardant, the expansion carbon film formed during burning shows the flame-retardancy due to insulating heat and air.There is low smoke, low toxic and non melting drop.So it is a kind of high efficiency environment protection inorganic flame-retardant. |
| Application range: |
| Crystalling phase Ⅱ ammonium polyphosphate has a wide range of use.It is suitable for plastic(PP, PVC , PE etc. ),polyester, rubber,various advanced expansion fire-retardant paint. |
| Package: |
| 25Kg/bag.The plastic bag has inner liner. | |
