  1, Product Name: Ammonium polyphosphate, type II. 2, Annual Capacity:5000MT 3, CAS No.: 68333-79-9 4, Molecular Formula: (NH4PO3)n 5, Physical & chemical properties: Ammonium polyphosphate’s (APP) molecular formula is(NH4PO3)n, n>1000. As inorganic chain polymer, there’s P-N collaboration effect because of high phosphorus and nitrogen content, so it has excellent fire retardant effect. It has good heat stability (decompounding temperature more than 275°C), low water-solubility (no more than 0.2g/100ml water), and it approachesneuterpolarity. It becomes the most important and widely used acid and gas stuff in chemistry expansive system. It can be compounded with other fire retardants, and it is of slight toxicity, (LD50>10g/kg). It can be applied in PE, PP, engineering plastic, rubber, fibre after surface modification. So it is named environment-friendly fire retardant. 6, Application: (1) Fire retardant additive in EVA, PE, POE, PP, PVC, PET and rubber (2) Fire retardant additive in paint and coating.. (3) Fire retardant additive in fiber material(paper, wood, fireproofing fabric and so on) (4) In synthetic fiber layer fire retardant. 9, Specification: Ammonium polyphosphate (Type II ), Degree of Polymerization>1000, white powder. 10, Packing: 25kg woven bag with plastic bag liner. 25MT per 20’FCL.

• Uses :

  As non-halogen flame retardant used in painting, plastic, textiles.
