CALCIUM BORATE is characterized as an environmentally friendly mineral based Flame Retardant Synergist developed as an alternative to Synthetic Zinc Borate in order to solve the thermal stability problem accompanied by Zinc Borate in plasticized PVC Applications, along with imparting superior Flame Retardant properties comparatively to Zinc Borate. The Flame Retardant action of Calcium Borate is mainly based upon its high Char Forming and Glazing/ Fluxing ability in combination with endothermic decomposition (Heat-Shrink Effect) and along with its inert water content (Loss on Ignition) which is quite higher as compared to traditional Zinc Borate which gives it an edge over it.
