Advantages of Semi-Metallic Brake Pads

  1. Superior Heat Management
    • High metallic content in the Brake Pads Mixes improves thermal conductivity, reducing brake fade during prolonged downhill braking.
  2. Extended Service Life
    • Steel fibers enhance wear resistance, achieving 40,000–60,000 km lifespan under typical truck loads.
  3. Cost-Effective Performance
    • Optimized brake pads formula balances copper-free requirements (per US EPA regulations) and friction stability, reducing total ownership costs by 15–20%.
  4. Adaptability to Harsh Conditions
    • Maintains friction consistency in wet, muddy, or high-salinity environments, ideal for mining and long-haul trucks.

Storage & Packaging Guidelines

  • Packaging:
    • Individually wrapped in anti-rust VCI (Volatile Corrosion Inhibitor) paper.
    • Stacked in reinforced wooden crates with shock-absorbent spacers.
  • Storage:
    • Temperature: -10°C–35°C in dry environments (max humidity 50% RH).
    • Avoid direct sunlight exposure; maximum stacking height: 8 layers.

Key Formula Components

The brake pads mixture includes:

  • Metallic Elements: Steel wool (25–35%), iron oxide (10–15%)
  • Friction Modifiers: Graphite (8–12%), cashew dust (5–8%)
  • Binders: Phenolic resin (12–15%) with hexamine curing agent

This brake pads formula is engineered for trucks requiring high torque braking capacity and compliance with global environmental regulations.
