white triclinic crystalline or amorphous powder, slightly soluble in water, crystals do not dissolve in hydrochloric acid, the amorphous powder dissolved in hydrochloric acid. Zinc borate is mainly used as the inorganic additives, non-toxic flame retardants for plastics, rubber, textile, paint and other industries.
Can be used as antimony oxide or other halogenated flame retardants multi-functional synergistic additives, can effectively improve the flame retardancy and reduce the generation of smoke when burned, and you can adjust the chemical, mechanical, electrical and other aspects of the performance of rubber products.
As part or completely environmentally friendly alternatives such as halogen-containing flame retardants are widely used in plastics and rubber processing directly, such as PVC, PE, PP, reinforced polyamide, polyvinyl chloride resin, polystyrene, epoxy resin, polyester and vinyl resins, natural rubber, styrene-butadiene rubber, chloroprene rubber.
It can be applied to paper, fabric, decorative panels, floor coverings, wallpaper, carpet, ceramic glaze, fungicides, paint production, in order to improve the flame retardancy.
It can also be used for corrosion protection, far-infrared absorption, timber pest biocontrol treatment and other fields.

Zinc borate is primarily used as a flame retardant in plastics and cellulose fibers, paper, rubbers and textiles. It is also used in paints, adhesives, and pigments. As a flame retardant, it can replace antimony trioxide as a synergist in both halogen-based and halogen-free systems. It is an anti-dripping and char-promoting agent, and suppresses the afterglow. In electrical insulator plastics it suppresses arcing and tracking. 1.As a non - dangerous product , this product can be transported and stored as a common chemical . 2.Usually , the product is packed for 25/40 kg|bag, but if needed , we can also pack as your instruction.
Zinc borate Commodity Name: Zinc Borate (3.5H2O) , ( Firebrake ZB 2335) Molecular Formula: 2ZNO, 3B2O3, 3.5H2O The Zinc Borate produced by our factory is also called FB Fire Retardant, ZB-2335 Fire Retardant or Firebrake ZB. Property: White crystal powder, without poison, flavor and corrosiveness. Doesn't dissolve in water and other organic solvent, is easy dissolved in hydrochloric acid & sulfuric acid, etc. Good thermal stability, small granule size, less specific gravity and easy dispersed. Good miscibility with most of the polymer. Fewest smoke when burning, excellent performance in inflaming retarding Certificate Of Analysis:Item Index Zinc Borate % 99 Apperance White crystal powder Boron Oxygenation (B2O3) % 48.0 í+ 3 Zinc Oxygenation (ZnO) % 38.0 í+ 2 Moisture (H2O) % í_1 specific gravity g/cm3 2.67 Residues on 350 meshú¿350-+ú¬% í_0.5 Temp of loss crystal water íµ 350í+50 Refractive index 1.58 Melting point íµ 980 Pb % 0.03 max Fe % 0.06 max As % 0.06 max Packing Inner plastic film with PP woven bags outside Net weight 25 kg/ Bag Loading Quantity 20MT or 22MT / 20'FCL 25KGS BAG
Flame Retardant Smoke Suppressant In contrast to antimony oxide, which promotes smoke formation, zinc borate reduces smoke emission Synergist with antimony oxide Use in conjunction with antimony oxide to give synergistic effect Synergist with Alumina Trihydrate (ATH) or Magnesium compounds Use in conjunction with alumina trihydrate or magnesium compounds such as magnesium hydroxide and magnesium carbonate to give synergistic effect Acid Suppressant Low HCl/acid value Afterglow Suppressant Char Promoter Form a glassy layer Corrosion Inhibition Used in flame retardant vinyl chloride latex formulations, as an adhesive in bonding fiberglass insulation to aluminum foil Low Tinting Strength Has a refractive index similar to most polymer systems, which results in the retention of considerable translucence, which allows the use of lower pigment loading as compared to antimony oxide Considered Low Toxicity
Zinc Borate is an inorganic compound, a borate of zinc. It is a white crystalline or amorphous powder insoluble in water. Its toxicity is low. Its melting point is 980 C.
Introduction: Zinc Borate is one environmental-friendly halogen-free flame retardant. There are some formulations of xZnO.yB2O3.zH2O, in which Zinc Borate with 3.5 hydrate is called ZBï¼?2335 (2ZnO.3B2O33.5H2O)is the most common used grade. It has owned some excellent properties on non-toxicity, slight solubility in water, good thermal stability, fine particle size, low specific gravity, great free-flowing etc. APPLICATIONS: 1. Zinc borate can be used as multi-functional synergistic additives with antimony oxide or other halogenated flame retardants to significantly improve the flame retardant performance, remove smoke emission and adjust the balance on chemical, mechanical, electrical etc properties. 2. As environmental protection substitute to replace current Antimony Oxide or halogen flame retardants, Zinc borate is directly used in PVC, PE, Polyolefin, Epoxy Polyamide etc resins and rubber process. Moreover, it is widely used in textile, fiber, floor, leather, wall paper, carpet, paint etc decorative materials to improve flame retardant performance. 3. Base on its anti static properties, zinc borate is widely used in mining plastic material, and used on anti-corrosion, infra red absorption, fungicide for wood preservation etc fields. Package: Stored in cool, dry and well ventilated environment. Packed and transported as normal chemical goods. Standard package is 25kg/bag
