Key Advantages
- Eco-Friendly Performance
The brake linings mixture contains no heavy metals, reducing hazardous dust emissions and aligning with global environmental regulations . - Superior Heat Resistance
Ceramic components ensure stable friction even at high temperatures, minimizing brake fade during prolonged use . - Low Wear and Longevity
Reinforced with aramid fibers, these brake linings friction materials exhibit exceptional abrasion resistance, ideal for high-mileage applications . - Noise Reduction
Organic additives (e.g., rubber particles) dampen vibrations, reducing squeal and improving driving comfort. - Compatibility
Compatible with both composite and cast iron brake drums, ensuring versatility in retrofitting .
Storage and Packaging
- Moisture Control: Packed in vacuum-sealed, moisture-proof bags to prevent degradation of organic binders .
- Temperature: Store in a dry environment below 35°C to avoid thermal expansion.
- Stacking: Limit to 4 layers to prevent deformation of the friction layer.
- Shelf Life: 18 months in unopened packaging.
Application of Brake Linings Mixes
The brake linings formula is molded under high pressure (10-20 MPa) and cured at controlled temperatures to ensure adhesion and structural integrity. Post-production testing includes thermal cycling (500+ cycles) and shear strength validation (≥3.5 MPa) . For customized requirements, manufacturers adjust the brake linings mixes ratio to optimize performance for specific vehicle models or operating conditions.
This innovative blend of ceramic and organic materials offers a sustainable, high-performance alternative to traditional metallic brake linings, meeting the demands of modern commercial transportation.
