Sodium antimonate can be employed in the rubber industry for its fire-retardant properties and other functionalities. Here’s how it can be used:

Fire Retardancy

Like in other applications, sodium antimonate acts as a fire retardant in rubber products by releasing water vapor and carbon dioxide when exposed to heat. This helps to suppress the spread of flames and reduce the combustibility of rubber materials, making them more fire-resistant. Rubber products treated with sodium antimonate can be used in environments where fire safety is a concern, such as automotive applications, construction, and electrical insulation.

Improving Mechanical Properties

Sodium antimonate can also enhance the mechanical properties of rubber materials. It can improve the tensile strength, tear resistance, and abrasion resistance of rubber compounds, making them more durable and suitable for demanding applications.


Sodium antimonate can act as a stabilizer in rubber formulations, helping to prevent degradation due to heat, light, and oxidative processes. This can extend the service life of rubber products and maintain their performance over time, especially in outdoor or high-temperature environments.

Processing Aid

In rubber processing, sodium antimonate can serve as a processing aid, facilitating the mixing, molding, and curing of rubber compounds. It can improve the dispersion of fillers and other additives in the rubber matrix, leading to more uniform properties in the final product.

Overall, sodium antimonate can be a valuable additive in the rubber industry, offering fire-retardant properties, improved mechanical performance, stabilization, and processing benefits. By incorporating sodium antimonate into rubber formulations, manufacturers can produce safer, more durable, and higher-quality rubber products for various applications.
