AKnoka® AP 400
| Name | Ammonium polyphosphate, APP |
| Grades | AKnoka™ AP 440 |
| CAS | 68333-79-9 |
| Molecular Formula | (NH₄PO₃)ₙ |
Product Description
Application: It is mainly used in intumescent fireproof coating and thermosetting resins (such as polyurethane hard foam, UP resin, epoxy resin, etc.), and can also be used in the flame retardant of fibers, wood and rubber and plastic products. Due to its high molecular weight (n>1000) and high stability, APP can also be used as the main active ingredient in intumescent flame retardant thermoplastics, especially in the manufacture of electronic components to UL 94-V0 PP.
Packing: 25kg/bag, paper bag, PE liner.
Storage and Transportation: Lightly carry and keep dry.
