At Bull Chemicals, our brake pads Silicon Carbide Powder serves as a critical functional additive in brake pads formula, delivering three core benefits that elevate braking performance and durability.

Brake Pads Silicon Carbide Powder
First, it acts as a high-efficiency abrasive and friction stabilizer. With a Mohs hardness of 9.2—second only to diamond—and a thermal conductivity of 120-200 W/(m·K), our SiC powder maintains consistent friction coefficients (0.35-0.45 under 80-350℃) even in extreme braking scenarios. This prevents “friction fade,” a common issue where high temperatures reduce stopping power, ensuring reliable braking for passenger cars, trucks, and industrial vehicles.
brake linings Silicon Carbide Powder
Second, it enhances wear resistance significantly. Tests show brake pads silicon carbide powder incorporating 5-8 wt% of our SiC powder (particle size: D50=8-15μm) exhibit a 30-40% lower wear rate compared to non-SiC formulations. This extends the brake pad service life from an average of 30,000 km to over 42,000 km, reducing replacement frequency and maintenance costs for end-users.
Car Brake Pads Metallic Mixture
Third, it improves thermal management. SiC’s high thermal conductivity facilitates rapid heat dissipation, keeping brake pad temperatures 50-80℃ lower during continuous heavy braking. This not only protects adjacent components (e.g., rotors, calipers) from thermal damage but also minimizes thermal expansion of the brake pad matrix, preserving dimensional stability and braking precision.
All our SiC powder meets ISO 10426-1 standards, with purity levels (98.5-99.5% SiC) and particle size distribution strictly controlled to ensure compatibility with various resin-based and semi-metallic brake pad matrices—making it a trusted choice for brake system manufacturers worldwide.
