Crystalline II ammonium polyphosphate (APP 801H)
Ammonium polyphosphate APP801H is higher polymerization degree than APP801H . It is more suitable to used in
plastic and polymer as
Flame Retardant. The pruduct is almost insoluble in water and
completely insoluble in organic solvent.
The benefits of our APP801H halogen free flame retardant:
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. In thermosets, can be used in conjunction with ATH, which allows a significant
reduction of the total FR filler
5. High polymerization degree ("n" value >2000), higher thermal stability and lower
water solubility than normal grade’s APP-II
