Zinc Borate (Hydrated / Commercial Grade)

CAS No 10361-94-1

Category

Synergists & Smoke Suppressants

Sub-Category

Zinc Borate

Description : Zinc Borate is a high-performance, white crystalline mineral additive universally used as a halogen-free flame retardant synergist, smoke suppressant, and polymer stabiliser, available in both zinc borate hydrated (CAS 1332-07-6) for standard processing under 290°C and zinc borate anhydrous (CAS 10361-94-1) for high-temperature engineering plastics processed above 300°C. While the hydrated grade dynamically releases chemically bound water to suppress smoke and cool fires, the anhydrous grade prevents high-heat polymer degradation and builds a robust protective char layer, meaning both grades effectively enhance fire resistance, smoke suppression, and thermal stability in PVC, polyolefins, elastomers, and coatings applications. Supplied as an industrial-grade powder or granular material, zinc borate is used extensively in industrial polymer compounding, cable insulation, and coatings manufacturing, delivering premium functional capabilities to meet strict regulatory fire standards. Also referred to as ZINC BORATE [HSDB] & ZINC BORATE [WHO-DD] by global manufacturers, we are the leading, trusted inorganic zinc borate supplier worldwide, providing both hydrated and anhydrous grades with reliable lead times and global supply capability.
