EXOLIT AP 428 is a fine-particle ammonium polyphosphate produced by a special method.

EXOLIT OP 1400 is a non-halogenated flame retardant based on organic phosphinates for reinforced polyamide 6, polyamide 66 and high temperature polyamides. The product achieves its flame retardant effect through a combined gas phase and condensed phase mode of action. Exolit OP 1400 is based on a new chemical substance which is currently being registered in various national and regional chemical inventories.

EXOLIT AP 435 is a fine-particle ammonium polyphosphate (phase II) optimized for low viscosity in aqueous suspension and intumescent coatings.

EXOLIT AP 740 is a white free flowing powder. It is a non-halogenated additive flame retardant based on ammonium polyphosphate which develops its effectiveness through phosphorus/nitrogen synergism.
