Sepiolite fiber has become a critical component in the production of high-quality friction materials, particularly in brake linings and clutch plates, where reliability and safety are paramount. Its unique properties—including high heat resistance, mechanical strength, and stability—make it an ideal additive for improving friction performance.
Friction materials require consistent friction coefficients across a wide range of temperatures to ensure smooth braking and prevent overheating. Sepiolite fiber, with its ability to withstand temperatures up to 300°C without degradation, helps maintain stable friction levels even during prolonged or heavy use. This reduces the risk of brake fade, a common issue in low-quality materials that can compromise vehicle safety.
Moreover, the fiber’s fibrous structure enhances the mechanical strength of friction materials, preventing cracking or wear under high pressure. When mixed with resins and other fillers, it improves the material’s bonding capacity, ensuring long-lasting durability. This reduces the need for frequent replacements, lowering maintenance costs for automotive and industrial applications.
Unlike some synthetic fibers, sepiolite fiber is non-abrasive, meaning it does not damage brake discs or drums during use. Its chemical inertness also ensures compatibility with other components in friction materials, such as binders and lubricants, without causing adverse reactions. For manufacturers prioritizing performance, safety, and cost-effectiveness, sepiolite fiber offers a natural, reliable solution to enhance friction material quality.
