Nyacol BurnEx ADP480 Colloidal antimony pentoxide Nyacol Flame and Smoke Retardants >> Antimony oxide Polyolefins (PE, PP…) ADHESIVE >> Hot-melt Nano-Dispersible Dry Powder Colloidal Antimony Pentoxide Flame Retardant Additives BurnEx™ A1582, BurnEx™ ADP480, BurnEx™ ADP494 Nyacol Nano Technologies, Inc. offers nano-dispersible dry powder colloidal antimony pentoxide for use as synergists with halogenated flame retardants in polymers, solvents and adhesives. Low chemical reactivity that will not interfere with electroless plating solutions Free-flowing particles for exceptional consistency, better mixing and easy processing Non-pigmenting for light transmission and mass tone colors Disperses to nano-size particles BurnEx A1582, BurnEx ADP480 and BurnEx ADP494 are powders made by spray drying aqueous solutions of colloidal antimony pentoxide. These grades are surface treated to aid dispersion to colloidal size. All are free-flowing agglomerates about 10-40 microns in size. BurnEx A1582, BurnEx ADP480 and BurnEx ADP494 act as synergists with halogen flame retardants. The nano-sized antimony pentoxide allows greater retention of the original physical properties in most systems. ADP 480 polyolefins, HIPS adhesives Stable and non-settling dispersions are formed in solvents with gentle mixing. Polymer solutions can be blended with such dispersions and will yield transparent films when dried. Epoxy resins can be blended with ADP494 dissolved in a ketone, and used to completely impregnate a reinforcement and produce a transparent laminate. ADP480 and ADP494 can be blended into ABS, HIPS and polypropylene in compounding equipment such as a twin screw extruder. Since both ADP480 and ADP494 contain some free and chemically bonded water, it is important that the compounding equipment be vented. In hot melt adhesive applications, some foaming may occur during the initial melt blending. Contact Nyacol Nano Technologies, Inc. for specific recommendations for compounding ADP480 and ADP494 in thermoplastics. Nano-dispersible dry powder colloidal antimony pentoxide. Used as a synergist with halogenated flame retardants in hot melt adhesives. Offers low chemical reactivity, free-flowing particles, good mixing and easy processing, and no pigmentation for light transmission and mass tone colors.
