Advantages of Garnet Powder in Brake Pads Formula
- Enhanced Friction Performance: Garnet’s high hardness improves the brake pads mixture by maintaining a stable friction coefficient (μ = 0.35–0.50), even under high-speed braking conditions.
- Wear Resistance: Reduces material degradation in brake pads friction materials, extending pad lifespan.
- Thermal Stability: Withstands temperatures up to 600°C, minimizing brake fade during prolonged braking.
- Noise Reduction: Acts as a damping agent, reducing squeal and vibration in brake pads mixes.
- Eco-Friendly: Free from asbestos and heavy metals, aligning with global environmental regulations.
Storage and Packaging Guidelines
To preserve the quality of brake pads mixes containing garnet powder:
- Packaging: Use moisture-resistant, UV-protected polyethylene bags with desiccants to prevent clumping.
- Storage Conditions:
- Temperature: 15°C–25°C (avoid thermal fluctuations).
- Humidity: <50% RH.
- Avoid direct sunlight and corrosive chemicals.
- Shelf Life: 18–24 months in unopened packaging.
Key Applications in Brake Pads Ingredients
Garnet powder is commonly blended with:
- Reinforcement Materials: Aramid fibers, steel wool.
- Binders: Phenolic resins or polyimide matrices.
- Fillers: Graphite, barium sulfate, and cashew dust.
This brake pads formula combination ensures high friction efficiency, durability, and compliance with automotive safety standards such as SAE J661.
Conclusion
Garnet powder’s unique properties make it a vital component in modern brake pads friction materials, offering superior thermal resilience, friction control, and environmental sustainability. Its integration into brake pads mixes exemplifies innovation in balancing performance and regulatory compliance for advanced braking systems.
Note: For optimal results, ensure garnet powder is uniformly dispersed in the brake pads mixture during production to avoid localized wear.
