Colloidal Antimony Pentoxide
Flame Retardant Additives

 

General Product Information

Nyacol Nano Technologies, Inc. offers colloidal antimony pentoxide in various forms for use as synergists with halogenated flame retardants.

 

Advantages

s    Better penetration of the substrate.

 

s    Greater cost effectiveness and improved color matching in mass tone colors.

 

s    Less pigmenting or whitening effect for deep mass tone colors.     

 

s    Translucency for applications such as coatings, films, and laminates.

 

s    Easier handling and processing; liquid dispersions will not clog spray guns.         

 

s    Suspension stability in low viscosity systems.

 

s    High flame retardant efficiency for minimal added weight or change in hand.

 

s    Maintenance of physical properties in thin films and fine denier fibers.

BurnExÔ Colloidal Antimony Pentoxide Powder

BurnEx Powders:

Aqueous dispersions of colloidal antimony pentoxide are spray-dried to make antimony pentoxide powders.  These powders will not tint the product because they are 10 to 40 micron agglomerates of nano-sized particles.  In situations where our available resin carriers are not compatible with your system, our regular powders are preferred.

BurnEx™ Nano-Dispersible Powders:

These powders of colloidal antimony pentoxide readily disperse to nanometer-sized particles in various solvents and polymers. Nyacol currently offers three nano-dispersible powders.

BurnEx™ A1582 disperses in water and has found use in vinyl and some thermoplastic polyesters.

BurnEx™ ADP480 is compatible with and disperses in non-polar hydrocarbons such as hexane and toluene, and in thermoplastics such as polypropylene.

BurnEx™ ADP494 disperses in polar compounds such as acetone, acetonitrile, and MEK. It is used for solvent-extended epoxy, solution spun fibers and thermoplastics such as ABS.

Polymer Concentrates:

BurnEx™ 2000

BurnEx 2000 polypropylene flame retardant concentrates are made from nano-dispersible antimony pentoxide and an organic bromine compound.  Polypropylene resins of different Melt Flow Index (MFI) are used for different applications.  Nyacol can design other concentrates or work with your compounder to formulate a custom product for you. We have a fully equipped compounding laboratory at our Ashland, Massachusetts facility.

Application

Usage Levels: 

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.  In textile, paper, and plastics applications, typical use levels of antimony pentoxide are 1.5 to 8%, with a halogen use level range of 5 to 20%.  Typical ratios of halogen to antimony are 5:1 to 2:1.
