Products

Exolit® AP 423 is a fine-particle ammonium polyphosphate produced by a special method. The crystal modification is phase II. The product is largely insoluble in water and completely insoluble in organic solvents. It is a white powder, non-hygroscopic and non-flammable.

Exolit® AP 435 is a fine-particle ammonium polyphosphate (phase II) optimized for low viscosity in aqueous suspension and intumescent coatings. The product is largely insoluble in water and completely insoluble in organic solvents. It is colorless, non-hygroscopic and non-flammable.

Exolit® AP 462 is a product based on ammonium polyphosphate. The crystal modification is phase II. It is manufactured from ammonium polyphosphate by micro-encapsulation with melamine resin according to Clariant’s own method. Exolit® AP 462 is a fine-particle white powder with very low solubility in water, even at elevated temperatures. It is completely insoluble in organic solvents. The product is non-hygroscopic and non-flammable.

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. Exolit® AP 740 differs in its mode of action from chlorine or bromine containing flame retardants by achieving its effect through intumescence. The flame retarded material foams on exposure to flame. The carbon foam layer so formed protects the polymer through its heat-insulating effect and reduces further oxygen access.

Exolit® AP 422 is a fine-particle ammonium polyphosphate (phase II) produced by a special method. The product is largely insoluble in water and completely insoluble in organic solvents. It is colorless, non-hygroscopic and non-flammable.

Exolit® 855 is a proprietary mixture containing liquid partial phosphoric acid esters for intumescent transparent fire protection applications for wood. The clear liquid is fully soluble in water, non-hygroscopic and non-flammable.

Exolit® AP 740 F 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. Exolit® AP 740 F differs in its mode of action from chlorine or bromine containing flame retardants by achieving its effect through intumescence The flame retarded material foams on exposure to flame. The carbon foam layer so formed protects the polymer through its heat-insulating effect and reduces further oxygen access.

Exolit® AP 422 A is a fine-particle ammonium polyphosphate (phase II) with less than 0.1% melamine. The product is largely insoluble in water and completely insoluble in organic solvents. It is colorless, non-hygroscopic, non-flammable, and classified as SVHC-free under current regulations.

Exolit® AP 428 is a fine-particle ammonium polyphosphate produced by a special method. The product is largely insoluble in water and completely insoluble in organic solvents. It is colorless, non-hygroscopic and non-flammable. Exolit® AP 428 differs from most other commercial products in the following ways: - greatly reduced solubility in water lower viscosity in aqueous suspensions - lower viscosity in PU polyol suspensions.
