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

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

EXOLIT OP 1230 is a white, fine-grained powder based on an organic phosphinate. The product is non-hygroscopic and it is insoluble in water and organic solvents. Clariant’s Exolit OP flame retardants for polyamides are all based on aluminium diethyl-phosphinate (= DEPAL). The pure substance DEPAL is sold as Exolit OP 1230 and in combination with synergists as Exolit OP 13xx types. Exolit OP 1230 is the first non-halogenated flame retardant which can withstand the demanding requirements of this high end segment of engineering plastics.

EXOLIT AP 462 is a product based on ammonium polyphosphate. The crystal modification is phase II.
