The features for Anhydrous Zinc Borate

(1) High heat resistance and flame retardant properties:

Compared to zinc borate with water, anhydrous zinc borate has a higher thermal decomposition temperature, with less than 1% weight loss at 400°C and remains stable at 600°C. When added to high-temperature processing polymer systems such as high-temperature nylon and polyester, it can effectively function as a flame retardant, inhibit combustion reactions, and enhance the flame retardant level of the material.

(2) Excellent physical and chemical stability:

Anhydrous zinc borate is non-toxic, odorless, insoluble in water and common organic solvents, and has stable physical and chemical properties. When compounded with various materials, it does not alter the original chemical properties of the materials and can also improve the tracking index, enhancing the overall stability of the materials.

(3) Multi-domain applicability:

Anhydrous zinc borate is applicable in various fields, playing a significant role in industries such as plastics, rubber, electronic products, and building materials. It reduces the flammability in plastic and rubber products; in electronic products, it protects the safety of electronic equipment; in building materials, it improves fire resistance; and it can also be used as a flame retardant and smoke suppressant in polymer systems that require high processing temperatures.

(4) Good environmental safety:

As an inorganic flame retardant, anhydrous zinc borate does not produce toxic or harmful gases during combustion, posing no harm to the environment and human health, and meets environmental protection requirements.

Packaging And Transportation Of Anhydrous Zinc Borate

Considering the characteristics of the Anhydrous Zinc Borate, Anhydrous Zinc Borate should be loaded and discharge lightly during transportation to prevent collision, rain, sun exposure, and pollution. Products should be stored in a ventilated, dry, and clean warehouse, and stacking is strictly prohibited.

The Packaging of Anhydrous Zinc Borate is 25kg/bag
