Flame Retardant FR-AP462

Formula: (NH4PO3)n n>1000
Molecular Weight: 79 ( number average)
CAS NO.: 68333-79-9
Physical appearance: fine, white powder, nontoxic, odorless.
Application: FR-AP462 is a flame retardant based on ammonium polyphosphate. It is manufactured by encapsulation with melamine resin according to Fairlands own method. It can be used in

-expanding fire-refractory coating(acid and solvent type);
-ire-refractory building board, coiled material;
-Thermal plasticity polyolefin
and unsaturated arene plastic;
-Isocyanurate foam;
-Epoxy resin and unsaturated resin;
-Cable and rubber;
-Plastic material of electron device;
-Fiber fabric.
Feature:
FR-AP462 differs from usual ammonium polyphosphate in the flowing properties:

marked reduction in water soluble constituents marked reduction viscosity in aqueous suspension marked enhance wetting out or compatibility with polymers or resins because it's surface energies changed. improved powder flowability improved spuming when exploded in fire increasing the of product added because it's lower phosphorus content

Packaging: 25kg woven bags.
Storage and transportation: Handle with care, keep airtight and dry.
