In the intricate world of chemical formulations, understanding the precise properties and applications of raw materials is critical for B2B buyers, R&D scientists, and product formulators. Zinc Borate, a versatile inorganic compound, has garnered significant attention primarily for its role as an effective flame retardant. This article serves as a guide for industry professionals looking to procure and utilize Zinc Borate, detailing its key characteristics and diverse application potential, while emphasizing the importance of sourcing from reputable providers.

Zinc Borate is recognized for its unique chemical structure, typically represented by formulas like 2ZnO·3B2O3·3.5H2O. It typically presents as a white powder, insoluble in water but with good dispersibility in many polymer matrices. A critical attribute for formulators is its high thermal stability, with decomposition temperatures often exceeding 290°C, making it suitable for processing at elevated temperatures common in the plastics and rubber industries. When you need to buy Zinc Borate flame retardant, these properties are paramount.

The primary application of Zinc Borate is as a flame retardant and smoke suppressant. It works through several mechanisms, including endothermic decomposition (releasing water vapor to cool the material), promotion of char formation (creating a protective insulating layer), and acting as a synergist with other flame retardant systems. This makes it invaluable in materials like PVC, polyolefins (PE, PP), polyamides, epoxy resins, and various rubbers. As a recognized eco-friendly flame retardant, it offers a safer alternative to some traditional halogenated compounds.

For procurement managers and R&D teams, identifying a reliable Zinc Borate supplier in China is crucial for ensuring consistent quality and competitive pricing. Factors to consider include the supplier's manufacturing capabilities, adherence to international quality standards, and their ability to provide technical support. A strong manufacturer will offer detailed product specifications, including purity levels (e.g., ZnO and B2O3 content) and physical characteristics like particle size and whiteness. Exploring options for halogen-free flame retardant price points will also guide purchasing decisions.

Beyond its flame-retardant properties, Zinc Borate also finds use as a corrosion inhibitor pigment and a fungicide in certain applications. Its versatility underscores its importance in various chemical formulations. By understanding its properties and collaborating with trusted suppliers, chemical industry professionals can effectively leverage Zinc Borate to enhance product safety and performance.
