First, it delivers exceptional lubrication and wear reduction.
With a layered structure (lamellar spacing: 0.335 nm) and flake size of 130–280 μm, it forms a stable lubricating film on the friction surface during braking. This cuts pad-disc friction by 21–24%, reduces pad wear by up to 29%, and extends service life by 2600–3100 km vs. standard fillers, lowering maintenance costs by ~18%.
Second, it excels at thermal management.
Boasting thermal conductivity of 125–175 W/(m·K) (vs. 3–5 W/(m·K) for mineral fillers), it dissipates braking heat fast. Braking from 105 km/h to stop, it limits pad temperature rise to 155–175°C (vs. over 285°C without it), preventing “brake fade.” The brake pads friction materials coefficient stays steady at 0.36–0.44 even after 9 minutes of continuous braking.
Third, it offers unbeatable stability.
With carbon purity ≥99.5% and ash ≤0.28%, it resists oxidation up to 600°C (organic fillers degrade at 300°C+). After 480 hours of salt spray tests, it retains structural integrity for harsh-environment reliability.
Fourth, it boosts manufacturing efficiency.
With bulk density 0.42–0.58 g/cm³, it mixes well with phenol-formaldehyde resin. It cuts agglomeration by 38%, improves mold filling by 34%, reduces defects to <1%, and lifts production efficiency by 14%.
At Bull Chemicals, our big flake graphite is a performance solution, helping make safer, longer-lasting brake pads for global markets.
