Advantages of Copper-Free Brake Pads
- Environmental Compliance
- The Brake Pads Mixes eliminate copper content, meeting EU Regulation No 458/2011 and U.S. Copper-Free Initiatives, reducing soil and water pollution.
- Enhanced Durability
- Composite brake pads friction materials (ceramic fibers + aramid pulp + steel wool alternatives) provide 20% longer lifespan than traditional copper-based pads.
- Heat Resistance
- Stable friction performance at 800°C, minimizing brake fade during prolonged downhill braking for trucks.
- Low Noise & Vibration
- Optimized brake pads formula reduces high-frequency noise (<75 dB) through embedded damping shims and hexagonal chamfer design.
Storage & Packaging Guidelines
- Packaging:
- Individually wrapped in corrosion-resistant, moisture-proof aluminum foil.
- Stacked on reinforced pallets (max 3 layers) with edge protectors.
- Storage:
- Temperature: 10°C–25°C in dry, UV-protected warehouses.
- Relative humidity: <50% RH (monitored via IoT sensors).
Key Formula Components
The brake pads mixture comprises:
- Friction Modifiers: Graphite (15–18%), zirconium silicate (10–12%)
- Binders: Modified phenolic resin (12–15%)
- Reinforcements: Ceramic fibers (30–35%), aramid pulp (8–10%), non-ferrous metallic particles (5–7%)
This copper-free brake pads formula achieves a balance between wear resistance and thermal stability, ideal for commercial trucks operating in mountainous or high-load scenarios.
