In the continuous pursuit of safer and more sustainable materials, the role of advanced flame retardants has become paramount. At NINGBO INNO PHARMCHEM CO.,LTD., we recognize the significant contribution of compounds like zinc borate to meeting stringent fire safety standards across a multitude of industries. This inorganic compound, particularly in its high-purity form, stands out as an eco-friendly and effective solution for preventing the spread of fire and reducing the hazardous effects of smoke.

Zinc borate's efficacy as a flame retardant stems from its unique chemical properties. When exposed to heat, it undergoes an endothermic decomposition process, releasing significant amounts of water vapor. This release of water has a dual purpose: it dilutes flammable gases in the combustion zone, thereby lowering the flame temperature, and it absorbs heat energy from the material. Crucially, the dehydration process also leads to the formation of a protective layer of molten boron oxide on the surface of the material. This glassy layer acts as a physical barrier, shielding the underlying substrate from oxygen and heat, thus inhibiting further combustion. This mechanism is a key reason why it's considered a superior inorganic flame retardant for plastics and other polymers.

One of the most compelling advantages of zinc borate is its nature as a halogen-free flame retardant. Unlike traditional halogenated flame retardants, zinc borate does not produce toxic or corrosive gases such as hydrogen halides when it burns. This makes it an environmentally responsible choice and contributes to improved safety for both workers and end-users. The demand for such halogen-free options is steadily increasing, driven by regulatory pressures and a growing awareness of environmental and health impacts. As a premier supplier, NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing these safer alternatives.

Furthermore, zinc borate exhibits remarkable synergistic effects when combined with other flame-retardant additives. For instance, it can be used in conjunction with alumina trihydrate, magnesium hydroxide, or ammonium polyphosphate in halogen-free systems. This synergistic capability allows for a reduction in the overall amount of flame retardant needed to achieve a desired level of fire resistance, leading to potential cost savings and without compromising performance. This makes it an excellent flame retardant synergist for polymers, enabling formulators to fine-tune their material properties.

The versatility of zinc borate extends to its application in a wide array of materials. It is extensively used in plastics such as PVC, PP, PE, and polyamides, as well as in rubbers, textiles, paper, coatings, and adhesives. Its ability to act as an anti-dripping agent and a char-promoting agent, while also suppressing afterglow, makes it invaluable for enhancing the overall fire safety characteristics of these materials. For example, in electrical insulator plastics, it helps to suppress arcing and tracking, which are common causes of electrical fires. The market for high purity zinc borate flame retardant is diverse and growing.
