ammonium polyphosphate phase II with epoxy treatment (APP-226)

description

Ammonium Polyphosphate phase II with epoxy resin treatment is a non-halogen flame retardant based on phosphorus/nitrogen synergism.  It is treated/coated by epoxy resin via a specialized method, and is free of formaldehyde.

 

Its solubility in water is very low and has less influence on polymers.  APP-226 is very suitable in epoxy resin, polyurethane, and textile coating systems.

 

packing

25 kg woven bag with plastic liner; 500/1000 kg super sacks.
