Product Form
  • BurnEx® ADP494 is a powder made by spray-drying aqueous solutions of colloidal antimony pentoxide.
  • It is surface-treated to aid dispersion to colloidal size.
  • The product is free-flowing agglomerates.
Product Function
  • BurnEx® ADP494 act as synergist with halogen flame retardant.
  • The nano-sized antimony pentoxide allows greater retention of the original physical properties in most systems.

Advantages Over Conventional Antimony Trioxide Systems
  • Low chemical reactivity will not interfere with electroless plating solutions.
  • Non-pigmenting for light transmission and mass tone colors.
  • Disperses to nano-size particles.
  • Free-flowing particles provide exceptional consistency, better mixing and easy processing.
  • Better penetration of the substrate.
  • Less pigmenting or whitening effect for deep mass tone colors.
  • Easier handling and processing: Liquid dispersions will not clog spray guns.
  • High flame retardant efficiency for minimal added weight or change in hand.
  • Greater cost effectiveness and improved color matching in mass tone colors.
  • Translucency for applications such as coatings, films, and laminates.
  • Suspension stability in low viscosity systems.
  • Maintenance of physical properties in thin films and fine denier fibers.

Product Uses
  • Solution-spun fibers
  • Epoxy-ketones
  • ABS
  • Surface treatment: Triethanolamine
Handling And Compounding
  • 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.
  • BurnEx® ADP480 can be blended into ABS, HIPS and polypropylene in compounding equipment such as a twin screw extruder.
  • BurnEx® ADP480 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.
  • Epoxy resins can be blended with BurnEx ADP494 dissolved in a ketone, and used to completely impregnate a reinforcement to produce a transparent laminate.
Usage Level
  • The usage level of the various grades depends on the material being treated, the test procedure, the ratio of halogen to antimony oxide, and other ingredients being used.
  • It is not possible to predict flame retardance performance; therefore, experimental evaluation is required.
  • Typical ratios of halogen to antimony are 5:1 to 2:1.
  • Typical use levels of antimony pentoxide are 1.5-8%, with a halogen use level range of 5-20%.
