In the production of friction materials, precipitated barium sulfate (BaSO4) has some applications to improve the performance:

Friction Modifiers

Barium sulfate can be used as a friction modifier in various friction materials, such as brake pads and clutch linings. It acts as a solid lubricant that reduces friction and enhances the performance and stability of these materials. By incorporating barium sulfate particles into the friction material matrix, it helps to improve the overall friction characteristics, reduce wear, and provide a smoother braking or clutch engagement experience.

Reinforcing Agent

Barium sulfate is also used as a reinforcing agent in friction materials. It enhances the mechanical properties and structural integrity of the final product. The addition of barium sulfate particles helps to increase the tensile strength, flexural strength, and impact resistance of the friction materials, making them more durable and capable of withstanding high-stress conditions.

Thermal Stability

Friction materials often operate under high-temperature conditions, especially in braking systems. Barium sulfate provides thermal stability to these materials by acting as an insulating barrier between the friction surfaces. It helps to dissipate heat generated during braking or clutch engagement, preventing excessive temperature rise and ensuring consistent performance over a wide range of operating temperatures.

Density Adjuster

Barium sulfate can be used as a density adjuster in friction materials. By adding specific amounts of barium sulfate, the density of the material can be tailored according to the desired specifications. This allows for better control over the overall weight and performance characteristics of the friction material while maintaining optimal frictional properties.

These properties contribute to improved performance, durability, and reliability of friction materials in automotive and industrial applications.
