Key Advantages
- Enhanced Durability
- The brake pads mixture contains 55-60% steel fibers and copper particles, reducing wear rates by 40% compared to conventional mixes.
- Average lifespan: 80,000–100,000 km under full-load conditions.
- Superior Heat Management
- High-density metallic brake pads friction materials maintain stable friction coefficients (>0.40) even at 700°C, preventing brake fade during downhill braking.
- Noise Reduction
- Integrated damping shims and chamfered edges lower noise levels to <75 dB at 60 km/h braking.
- Corrosion Resistance
- Zinc-coated backing plates and silica-reinforced Brake Pads Mixes prevent rust formation in humid/salty environments.
Storage & Packaging Specifications
- Packaging:
- Individually wrapped in anti-corrosion VCI film.
- Stacked on reinforced wooden pallets (max 20 layers) with edge protectors.
- Storage:
- Temperature: -10°C to 35°C in dry environments (max humidity 65% RH).
- Avoid direct sunlight; rotate stock quarterly to prevent deformation.
Formula Composition Breakdown
The brake pads formula comprises:
- Metallic Components: Steel fibers (30–35%), copper powder (15–20%)
- Friction Modifiers: Graphite (8–10%), barite (12–15%)
- Binders: High-temp phenolic resin (10–12%)
- Reinforcements: Aramid pulp (5–7%), ceramic microspheres (3–5%)
This high-density brake pads mixture ensures optimal performance for mining trucks, freight haulers, and other heavy commercial vehicles.
