When discussing high-performance brake pads, the role of Wollastonite in optimizing Brake Pads Friction Materials cannot be overstated. As a critical inorganic additive, Wollastonite is specifically engineered to address core challenges in brake pad performance—from heat resistance to friction stability—making it an indispensable component in modern Brake Pads Formula.

Brake Pads Wollastonite
In Brake Pads Mixture production, Wollastonite is typically incorporated at a precise dosage of 15-25% by weight. This concentration is not arbitrary: its acicular (needle-like) particle structure (with an aspect ratio of 8:1 to 12:1) acts as a “mechanical skeleton” within Brake Pads Mixes, significantly enhancing the material’s mechanical strength. Tests show that brake pads containing Wollastonite exhibit a 20-30% higher flexural strength (reaching 18-22 MPa) compared to those without, reducing the risk of cracking or fragmentation under sudden braking forces.

Thermal stability is another key advantage. Wollastonite maintains its structural integrity up to 1540°C, far exceeding the maximum operating temperature of brake pads (usually 300-600°C). This property prevents thermal degradation of the brake pads friction materials, ensuring consistent friction coefficients (0.35-0.45) across temperature fluctuations—critical for avoiding “brake fade” (a dangerous drop in stopping power at high temperatures).

Additionally, Wollastonite improves wear resistance and reduces noise. Its low abrasiveness (Mohs hardness of 4.5-5) minimizes wear on both the brake pad and rotor, extending the pad’s service life by 15-20%. Simultaneously, its ability to absorb vibration within the brake pads mixture lowers braking noise by 3-5 decibels, enhancing driving comfort.
In summary, Wollastonite is not just an additive but a performance enhancer: it strengthens brake pads mixes, stabilizes friction, resists heat, and reduces wear—all while aligning with the strict durability and safety standards that define high-quality brake pads.
