First: Stabilizes Friction Coefficient Under Extreme Temperatures
brake pads white rock wool’s fibrous structure integrates tightly into brake pads mixture, resisting thermal degradation. In our tests, brake pads with 4-6% White Rock Wool in their brake pads formula maintained a friction coefficient of 0.42-0.48 (ASTM D4472) from -40°C to 600°C, cutting fluctuation by 20% vs. traditional materials . Its low thermal conductivity (0.038-0.042 W/(m·K)) ensures consistent braking even in high-stress scenarios.
Second: Boosts Wear Resistance and Lifespan
As a reinforcing component in brake pads mixes, White Rock Wool enhances the durability of brake pads friction materials. Tested under ISO 6469-3 standards, these brake pads show a wear rate of 0.08-0.12 mm/1000 km, extending service life by 30% . With a melting point ≥1700°C, it minimizes material loss during braking, reducing maintenance costs.
Third: Enhances Formula Compatibility and Processability
White Rock Wool’s inert nature ensures seamless integration with resins and abrasives in brake pads mixture. It disperses uniformly in brake pads mixes, lowering production defects by 18% and adapting to both semi-metallic and NAO brake pads friction materials . Its adjustable 3-8mm fiber length allows precise tuning for diverse performance needs.
Bull Chemicals leverages White Rock Wool to empower brake pad manufacturers with reliable, high-performance solutions. It’s an indispensable addition to brake pads mixture, brake pads mixes, and brake pads formula, elevating safety and durability for global clients.
