The features for Zinc Borate 3.5-Hydrate

(1) High-efficiency flame retardant performance:

Zinc Borate 3.5-Hydrate has excellent flame retardant effects. When added to materials such as plastics, rubber, and coatings, Zinc Borate 3.5-Hydrate can effectively improve their flame retardant levels.

(2) Good chemical stability:

Zinc Borate 3.5-Hydrate is non-toxic, odorless, and chemically stable. Zinc Borate 3.5-Hydrate is insoluble in water and common organic solvents. When used in combination with various materials, Zinc Borate 3.5-Hydrate does not affect the original chemical properties of the materials but can enhance the overall stability of the materials and extend their service life.

(3) Wide range of applications:

Zinc Borate 3.5-Hydrate can be widely applied in various industries. In the plastic industry, it can enhance the flame retardancy and overall performance of plastics; in the rubber industry, Zinc Borate 3.5-Hydrate can increase the flame retardant capability of rubber products; in the coatings field, Zinc Borate 3.5-Hydrate can be used to produce fire-retardant coatings; in the production of ceramic glazes, Zinc Borate 3.5-Hydrate can act as a flux to lower firing temperatures. Zinc Borate 3.5-Hydrates versatility makes Zinc Borate 3.5-Hydrate an indispensable additive for many materials.

(4) Outstanding environmental protection characteristics:

As a non-halogen flame retardant, Zinc Borate 3.5-Hydrate does not produce toxic and harmful gases when burned, unlike traditional halogen-containing flame retardants, thus reducing harm to the environment and human health.


Packaging And Transportation Of Zinc Borate 3.5-Hydrate

Considering the characteristics of the Zinc Borate 3.5-Hydrate, Zinc Borate 3.5-Hydrate 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 Zinc Borate 3.5-Hydrate is prone to moisture and should be stored in a cool, dry place. If the packaging is damaged, use as soon as possible. If the package is found to be broken or damp, dry at 100℃±10℃ for 2 hours before use.


The Packaging of Zinc Borate 3.5-Hydrate is 25kg/bag
