UsageIndustrial, Laboratory
Commercial Name: ZB fire-retardant Chemical name: Low Water Zinc Borate General Formula: 2ZnO.3B2O3.3.5H2O Zinc Borate can be used as afire retardant in PVC, Polyolefins, Elastomers, Polyamides, Epoxy resins. In halogen-containing systems, Zinc Borate is used in conjunction with antimony oxide, while in halogen-free systems, it is normally used in conjunction with aluminium trihydrate, magnesium hydroxide, or red phosphorus. In some particular application Zinc Borate can be used alone.

Magnesium Hydroxide is Non-Halogenated, High thermal stable non corrosive smoke suppressant and acid scavenger. Its high thermal stability - up to 340C enables its use where Aluminum trihydrate is not sufficiently stable.

Magnesium Hydroxide provides flame retardance through FIVE mechanisms:
  • Magnesium Hydroxide produces more char than ATH resulting in increased effectiveness and less smoke.
  • Magnesium Hydroxide dilutes the amount of fuel available to sustain combustion.
  • Magnesium Hydroxide during combustion, generates highly reflective magnesium oxide coating which deflects the flame's heat away from the polymer.
  • Magnesium Hydroxide contains 31 % bound water which is released beginning at 330" C and blankets the flame to limit oxygen available for combustion.
  • Magnesium Hydroxide absorbs 17% more heat from the combustion zone than ATH to reduce the prospect of continued burning.
