Exolit® AP 422 A

Exolit® AP 422 A by Clariant is a fine-particle, non-halogenated ammonium polyphosphate flame retardant with less than 0.1% melamine. It is a favorable environmental and health profile colorless, non-hygroscopic, biodegradable, non-flammable grade free of SVHCs. It is effective in cellulose-containing materials such as paper and wood products, and polyolefin-based wood plastic composites (WPC) with high wood contents (>50%).

• It has extremely low vapor pressure, water solubility, acid number and viscosity in aqueous suspensions.
• It is suitable for various PUR applications including flexible polyester-based PUR foams, with minimum impact on reaction profiles and material properties.
• It is an essential component in intumescent formulations for thermoplastics, particularly polypropylene, for which the classification UL 94-V0 is specified for applications in the electrical sector.
• In the case of thermosets like epoxy resins and unsaturated polyester resins, it paves the way for the production of lightweight components with low solids content.
• Exolit® AP 422 A can be used in transport applications to obtain good fire, smoke, and toxicity results, E&E, and consumer applications.
• It has a shelf life of 12 months.
