It delivers exceptional thermal resilience.
Test data shows it maintains consistent performance at -40°C to 350°C. Even at 300°C, its brake pads friction materials coefficient fluctuation is ≤0.03, well below the industry’s 0.08 maximum allowable limit, effectively preventing brake fade in high-speed or heavy-duty braking.
It enhances wear resistance significantly.
Brake pads with 8-12% CNSL Friction Dust—the optimal dosage verified by R&D—reduce rotor wear rate by 15-20% versus conventional formulations. Per 50,000+ simulated braking cycle tests, the pad’s service life extends by 25% on average.
It minimizes noise and vibration.
Its unique lamellar structure dampens friction-induced vibration. Brake pads integrated with it achieve ≤55dB noise in 90% of braking events, meeting the strict EU ECE R90 standard.
Bull Chemicals provides high-purity CNSL Friction Dust, with cashew phenol content ≥85% and particle size D50 controlled at 15-25μm. This ensures seamless integration into diverse brake pad recipes, enabling manufacturers to produce safer, longer-lasting, and more reliable braking solutions.
