Zinc Borate

Flame Retardant

Smoke Suppressant

In contrast to antimony oxide, which promotes smoke formation, zinc borate reduces smoke emission

Synergist with antimony oxide

Use in conjunction with antimony oxide to give synergistic effect

Synergist with Alumina Trihydrate (ATH) or Magnesium compounds

Use in conjunction with alumina trihydrate or magnesium compounds such as magnesium hydroxide and magnesium carbonate to give synergistic effect

Acid Suppressant

Low HCl/acid value

Afterglow Suppressant

Char Promoter

Form a glassy layer

Corrosion Inhibition

Used in flame retardant vinyl chloride latex formulations, as an adhesive in bonding fiberglass insulation to aluminum foil

Low Tinting Strength

Has a refractive index similar to most polymer systems, which results in the retention of considerable translucence, which allows the use of lower pigment loading as compared to antimony oxide

Considered Low Toxicity
