Commercial Name: Ammonium Polyphosphate 231
Product No.: CS FR APP 231
H.S. Code: 2835399000
CAS No.: 68333-79-9
Chemical Formula: (NH4PO3)n n≥1000
Executive Standard: HG/T2770-2008
Benefits:
1. Halogen and formaldehyde-free, non-toxic and does not generate additional quantities of smoke.
2. Requires lower loadings ensuring lower cost, better properties retention and excellent flow.
3. Exhibits excellent processability, good retention of mechanical and electrical properties in thermoplastic formulations.
4. High polymerization degree ("n" value > 1000), higher thermal stability and lower water solubility than APP-I.
