Zinc Borate. Zinc Borate is a flame retardant / smoke suppressant in polyamides, PVC, polyethylene, polypropylene, epoxy, polyesters, elastomers and rubber based formulations.The particle size and refractive index of ZB results in the product having very little pigmenting power (tinting strength), minimizing pigment loading and in translucent formulations.
Zinc borate Unknown EPA Applications/Systems. Below are the EPA applications/systems, statutes/regulations, or other sources that track or regulate this substance. This table shows how each list refers to the substance. To view more metadata about the specific Synonym, click on the Synonym.
Zinc borate is prepared as an insoluble double salt from water-soluble zinc and boron compounds. Compounds having varying amounts of zinc, boron, and water of hydration are available. The ratio of these components affects the temperature at which the flame-inhibiting powers are activated, as well as the temperature at which they can be processed.
