Introduction to White Rock Wool in Brake Pads Formulas
White Rock Wool, a high-purity mineral fiber derived from volcanic basalt and processed through advanced refining techniques, plays a pivotal role in modern brake pads mixtures. Its unique composition enhances thermal resistance, noise suppression, and mechanical stability in Brake Pads Friction Materials. Below is a detailed technical overview of its application in Brake Pads Mixes, along with advantages and storage protocols.
Technical Parameters of White Rock Wool in Brake Pads Formula
| Parameter | Value/Range | Notes |
|---|---|---|
| Fiber Diameter | 2–5 μm | Ensures uniform dispersion in resin matrices |
| Density | 75–110 kg/m³ | Lightweight yet structurally robust |
| Thermal Resistance | Up to 900°C | Prevents brake fade under extreme conditions |
| Acoustic Damping | 30–40 dB reduction | Effective in reducing high-frequency noise |
| Content in Formula | 10–18% (by weight) | Balances friction stability and wear resistance |
Key Advantages of White Rock Wool in Brake Pads Mixture
- Superior Thermal Stability: Withstands temperatures exceeding 900°C, maintaining consistent friction coefficients (0.35–0.45 μ) even during aggressive braking.
- Noise and Vibration Control: Its porous fiber structure absorbs kinetic energy, reducing NVH (Noise, Vibration, Harshness) by 35% compared to conventional materials.
- Eco-Friendly and Safe: Asbestos-free, recyclable, and compliant with global safety standards (e.g., EU Regulation No. 305/2011).
- Enhanced Matrix Integrity: Reinforces Brake Pads Ingredients like ceramic particles and phenolic resins, reducing wear rates by 25%.
Storage and Packaging Guidelines
- Moisture Protection: Store in vacuum-sealed, aluminum-laminated bags (humidity <5%) to prevent fiber clumping and hydration.
- Temperature Limits: Maintain storage conditions below 35°C to preserve pre-coated resin integrity.
- Dust Management: Use electrostatic precipitation systems during handling to minimize airborne particles.
Integration with Brake Pads Ingredients
White Rock Wool is synergistically blended with:
- Friction Modifiers: Ceramic microparticles (10–20%) and molybdenum disulfide (5–10%) for stable friction output.
- Binders: High-temperature phenolic resins (15–20%) with low VOC emissions.
- Fillers: Barium sulfate (8–12%) to balance thermal expansion and corrosion resistance.
This optimized brake pads formula achieves a wear rate of ≤0.12 mm/1,000 km in urban driving cycles.
Conclusion
White Rock Wool exemplifies innovation in brake pads friction materials, combining extreme thermal resilience, acoustic comfort, and environmental sustainability. Its integration into brake pads mixes aligns with the automotive industry’s shift toward high-performance, eco-conscious solutions. Strict adherence to storage protocols ensures material efficacy, making it indispensable for OEM and aftermarket applications.
