For brake system manufacturers, consistent friction stability in brake pads friction materials starts with additive precision—and Bull Chemicals’ Heavy Calcium Carbonate delivers exactly that, via tailored particle size. As a core component in brake pads mixture and formulas, it solves key friction fluctuation challenges. Below’s the breakdown.

First: Fine Grade (D50=3-5μm) for Uniform Friction
Our fine Heavy Calcium Carbonate disperses evenly in brake pads mixes, eliminating “hard spots.” It keeps friction coefficient fluctuation within ±3% (200-400℃), cuts passenger car brake noise by 15%, and maintains a steady 0.38-0.42 coefficient.
Second: Medium Grade (D50=8-10μm) for Stability & Durability
Ideal for heavy-duty brake pads friction materials, this grade (10-12% in brake pads mixture) resists 600℃ thermal degradation, reducing friction coefficient drop by over 20%. It extends brake pad life to 60,000+ km—10% longer than random particle sizes.
Third: Controlled Distribution for Formula Compatibility
With narrow particle size distribution (D90-D10 ≤5μm), our product fits organic/semi-metallic brake pads formulas. It boosts component bonding by 12%, locks in stability (-30℃ to 650℃), and saves 8% in production costs by avoiding rework.
Bull Chemicals’ Heavy Calcium Carbonate is a precision tool for brake pads friction stability—tailored particle sizes seamlessly integrate into your brake pads mixture and formula.
