EM Sullivan Associates, a North American specialty chemical and fine ingredient distributor is pleased to introduce two specialty products from Nyacol. NYACOL NYAGRAPH and Colloidal Antimony Pentoxide, two new flame-retardant additives.

NYAGRAPH is an expandable graphite flame-retardant additive that is a natural material based on the processing of graphite ore. NYAGRAPH Expandable Graphite may be used in polyurethanes, sealants, bitumens, rubbers, adhesives, coatings, and polymers. It may also be used in conjunction with other flame-retardants to provide improved flame-retardant and smoke-suppressant properties to a material.

Nyacol NYAGRAPH Expandable Graphite is an intumescent flame-retardant additive that offers the following advantages:

  • Halogen-free
  • Low smoke
  • Reduced heat release
  • Insulating
  • Lower in toxic gases
  • Non-dripping

Colloidal antimony pentoxide, a flame-retardant additive, is available in various forms for use as synergists with halogenated flame-retardants. Advantages include:

  • 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.

These flame-retardant additive products are available in organic dispersions, colloidal antimony powders, nano-dispersible powders and polymer concentrates.
