Since Zinc Borate3.5H2O (cas 1332-07-6 ) releases its water of hydration at temperatures exceeding 290°C (554°F), it can be used in requiring high processing temperatures. Zinc Borate 1332-07-6 has a refractive index comparable to that of most polymer systems, which outcomes in the retentio of significant translucency and lets in the use of low pigment loading. It can be fed to extruders, calenders, or injection molding gear in a whole lot the identical way as different polymer additives.Zinc Borate3.5H2O (cas 1332-07-6 ) is used as a flame retardant, smoke and afterglow suppressant, and anti-arcing agentin polymer structures such as polyvinyl chloride, nylon, epoxy, polyethylene, polypropylene, polyesters, thermoplastic elastomers and rubbers Depending on the base polymer used and hearth requirements to be met, Zinc Borate3.5H2O (cas 1332-07-6 ) can be used to substitute in part (or even completely) different furnace retardant components such as antimony oxide
