Introduction to Rock Wool in Brake Pads Formula
Rock wool, a mineral fiber derived from volcanic rock or slag, is a critical component in brake pads formulas due to its thermal resistance, structural stability, and compatibility with Brake Pads Friction Materials. This article explores its technical specifications, advantages, and storage guidelines in Brake Pads Mixes, emphasizing its role in enhancing braking performance and safety.
Technical Parameters of Rock Wool in Brake Pads Mixture
The table below outlines key technical properties of rock wool in Brake Pads Ingredients:
| Parameter | Value | Test Standard |
|---|---|---|
| Fiber Diameter | 4–7 μm | ISO 137 |
| Operating Temperature | Up to 700°C | ASTM D3418 |
| Density | 1.2–1.5 g/cm³ | ISO 1183 |
| Tensile Strength | 300–500 MPa | ASTM D638 |
| Melting Point | >1,000°C | ISO 11357 |
| Fiber Content in Formula | 10%–25% by weight | Internal QC Protocols |
Advantages of Rock Wool in Brake Pads Formula
- Exceptional Heat Resistance: Rock wool withstands extreme temperatures (up to 700°C), preventing brake fade and maintaining friction stability in high-stress conditions.
- Noise Reduction: Acts as a vibration-damping agent, reducing squeal and noise in brake pads friction materials.
- Enhanced Durability: Reinforces the brake pads mixture by improving wear resistance and mechanical strength.
- Fire Safety: Non-combustible properties align with automotive fire safety standards.
- Eco-Friendly: Asbestos-free composition complies with global environmental regulations.
Storage and Packaging Guidelines
To preserve the integrity of brake pads mixes containing rock wool:
- Packaging: Use sealed, moisture-resistant polyethylene bags with desiccants to prevent humidity absorption.
- Storage Conditions:
- Temperature: 10°C–35°C (avoid thermal fluctuations).
- Humidity: <60% RH.
- Protect from UV exposure and corrosive substances.
- Shelf Life: 18–24 months in unopened packaging.
Applications in Brake Pads Ingredients
Rock wool is integrated into brake pads formula alongside:
- Reinforcement Materials: Aramid fibers, steel wool.
- Binders: Phenolic resins.
- Fillers: Graphite, barium sulfate.
For example, LAPINUS RB220 and RB250 rock wool fibers are widely used in brake pads friction materials for motor vehicles, ensuring durability and compliance with industry standards.
Conclusion
Rock wool’s thermal resilience, noise-reduction capabilities, and environmental safety make it indispensable in modern brake pads mixtures. Its integration into brake pads ingredients exemplifies innovation in automotive engineering, delivering reliability and performance for high-demand braking systems.
