Royce Zinc Borate No.:12767-90-7

  

Zinc Borate CAS  NO.12767-90-7 / 138265-88-0/1332-07-6/1332-07-6

Zinc borate is  a unique form of zinc borate with multifunctional fire retardant applications in plastic and rubber compounds. Since ZB2335 releases its water of hydration at temperatures exceeding 290°C (554°F), it can be used in systems requiring high processing temperatures. ZB2335 has a refractive

index similar to that of most polymer systems, which results in the retention of considerable translucency and allows the use of low pigment loading. It can be fed to extruders, calenders, or injection molding  equipment in much the same way as other solid polymer additives.

Application  

used as a flame retardant, smoke and afterglow suppressant, and anti-arcing agent

in polymer systems such as polyvinyl chloride, nylon, epoxy, polyethylene, polypropylene, polyesters, thermoplastic elastomers and rubbers

Depending on the base polymer used and fire standards to be met, Firebrake® ZB can be used to

replace partially (or even completely) other fire retardant additives such as antimony oxide

Storage:  Store in dry, normal temperature, moisture prevention
