Antimony Trioxide, a natural product called antimony white, is a white crystalline powder. It turns yellow when heated and turns white when cooled. It has no odor, with a melting point of 655℃ and a boiling point of 1550℃.

The chemical formula of zinc borate is 2ZnO · 3B ₂ O3 · 3.5H ₂ O, which is a white crystalline or amorphous powder. Its molecular structure contains zinc ions (Zn ² ⁺), borate ions (BO ∝⁻), and crystal water. This structure endows zinc borate with the following characteristics:

Zinc borate, as an important inorganic additive, plays an irreplaceable role in the rubber industry. This white crystalline powder, with its unique chemical properties, exhibits multiple functions in the production of rubber products, from flame retardancy to smoke suppression, from reinforcement to corrosion resistance, endowing rubber materials with superior performance.

Zinc borate is a white crystalline or amorphous powder with the chemical formula 2ZnO · 3B ₂ O3 · 3.5H ₂ O. It has low water solubility and good thermal stability, and is generally considered a low toxicity substance. However, the boron and zinc elements it contains may have certain effects on the skin under specific conditions.
