First, it ensures balanced friction.
As a key modifier, 8-15% addition maintains a 0.38-0.48 friction coefficient at 50°C-400°C, vs. ±0.12 fluctuations without it. Our infused pads have a ≥0.85 friction stability index, meeting ECE R90 standards.
Second, it reduces wear.
With Mohs hardness 6-6.5, 10-12% iron pyrite leads to 0.15-0.18 mm/1000 cycles pad wear and ≤0.005 mm/1000 cycles disc wear (150°C, 550N). This cuts disc replacement by 30% vs. traditional fillers.
Third, it boosts thermal performance.
With 1171°C melting point and 12-15 W/(m·K) thermal conductivity (1.5-2x organic modifiers), it lowers pad surface temperature by 15-25°C during braking, preventing friction fade and resin decomposition above 350°C.
Fourth, it optimizes cost-effectiveness.
As a substitute for copper/brass powders, it cuts raw material costs by 20-25% while ensuring ≥50,000 km service life. Its ≤0.5% moisture content reduces production defects by 18%.
Bull Chemicals tailors specs (particle size, purity) for passenger cars, commercial vehicles, and machinery. Strict quality control ensures consistent performance. Brake pads iron pyrite powder balances stability, wear reduction, and cost, and we’re committed to delivering quality products and technical support.
