Zinc Borate is a white crystalline mineral additive universally used 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 industrual grade powder or granular material, Zinc Borate is used extensively in industrial polymer compounding, cable insulation, and coatings manufacturing and has a fine functional capabilities. Also referred to as ZINC BORATE [HSDB] & ZINC BORATE [WHO-DD] by Zinc Borate manufacturers. We are the leading, trusted sodium Zinc Borate supplier worldwide and in the United States, with reliable lead times and global supply capability.

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.
