Halogen/Antimony Pentoxide Concentrate 


BurnExÔ 2000-10

Nyacol Nano Technologies, Inc. offers concentrates for use as flame retardants in polyolefins.

Advantages over a conventional antimony trioxide system 

·          Non-pigmenting for light transmission and deep mass 
tone colors.

·          Physical properties are retained.

·          Nano-sized particles are predispersed.




The BurnEx™ 2000 series of flame retardant concentrates was developed for the polyolefin market. These concentrates are made from nano-sized, fully dispersed antimony pentoxide and melt blendable brominated flame retardant in polypropylene.  Processing with BurnEx 2000 yields superior physical characteristics.  In some cases, the finished product maintains the physical properties equivalent to the virgin polymer.  Cast and blown films, fine denier yarns and monofilament lines and other polypropylene materials needing flame retardancy are candidates for these concentrates.

BurnEx™ 2000-10 is recommended for blow-molding or injection molding applications. 


These concentrates come as degassed, predispersed
halogen/antimony pentoxide in 1/8" polypropylene pellets.
