Zinc Borate is a white crystalline mineral additive used universally as a halogen-free flame-retardant synergist, smoke suppressant, and polymer stabilizer. Zinc Borate enhances fire resistance, smoke suppression, and thermal stability in PVC, polyolefins, elastomers, and coatings applications. Supplied as industrial-grade powder or granular material, Zinc Borate is used extensively in industrial polymer compounding, cable insulation, and coatings manufacturing, and offers fine functional capabilities. Also referred to as ZINC BORATE [HSDB] & ZINC BORATE [WHO-DD] by Zinc Borate manufacturers. As one of the specialized Zinc Borate manufacturers and suppliers serving the U.S. market, we deliver bulk technical-grade material produced through controlled precipitation, filtration, particle size classification, and moisture-control processes to ensure consistent chemical composition and reliable performance in flame-retardant systems. Zinc Borate products are supported by comprehensive quality and regulatory documentation, including Certificates of Analysis (CoAs), Safety Data Sheets (SDSs), specification sheets, and full batch traceability, all aligned with applicable U.S. Standards

Chemical Properties & Specifications
H319: Serious eye damage/eye irritation
P264+P265, P280, P305+P351+P338, and P337+P317
Enhances thermal stability and fire resistance in PVC, polyolefins, elastomers, and engineering plastics
Smoke suppressant in (PVC, PE, PP, EVA, epoxy resins). Improves thermal stability of polymer systems. Reduces smoke density during combustion
Preferred in intumescent coatings, paints, and sealants. Improves chemical resistance and weatherability
Acts as halogen-free synergist, stabilizer, and smoke suppressant in flame retardant systems
Enhances arc resistance and tracking resistance in electrical components. High preferrence for wire & cable insulation, circuit boards, housings
Rubber conveyor belts, hoses, gaskets for flame resistance
Used in roofing, flooring, wall panels, insulation materials
Store at 15–30 °C
Keep dry and sealed, avoid direct moisture
Up to 3 years under recommended storage conditions
Use PPE (gloves, dust mask, goggles); avoid dust inhalation
Used as a halogen free flame retardant, smoke suppressant, and polymer stabilizer in PVC, polyolefins, elastomers, and coatings.
Endothermic decomposition upon heating. Starting around 290 °C, it releases water of hydration. Release of water vapor cools the material, dilutes flammable gases, and promotes the formation of a protective glassy char layer.
Polymer compounding, cable insulation, coatings, elastomer production, and industrial R&D laboratories.
PVC, polyolefins, elastomers, and engineering plastics requiring halogen-free flame retardancy.
Enhances fire resistance, thermal stability, and smoke suppression, acting as a halogen-free flame retardant synergist.
