مزايا
  • His refractive index is 1.57, similar to that of many polymeric matrices allowing the use of lower charges of pigments.
  • It promotes the formation of a protective vitreous layer and of a strong char layer, which prevents the oxidation of carbon by limiting the available oxigen and suppresses smoke production.
  • It acts as a synergist in conjunction with halogenated compounds, so that lower loadings of halogenated flame retardant additives are needed, in this way reducing the formation of corrosive smokes during fire.
  • Its strong synergic effect with antimony trioxide allows sensible savings due the higher costs of antimony trioxide.
  • In presence of alumina trihydrate (ATH), the synergic effect is enhanced even at lower charges of additives.
  • It provides an improved resistance against electrical degradation: high anti arcing and anti-tracking indexes.

معاملة

It is insoluble in water, alcohol, benzene and acetone, easy soluble in hydrochloric acid, sulphuric acid and dimethyl sulfoxide.
It looses its water of hydration at temperatures above 290°C, cooling the front of the flames and subtracting energy to the fire with an endothermic reaction.
ZINBOREL® is largely used in PVC formulations due to its strong synergic effect with antimony trioxide.
