Reinforced with steel and copper, the brake linings friction materials exhibit minimal material loss, ideal for high-mileage commercial vehicles. - Low Noise and Vibration
Optimized porosity and ceramic additives reduce squeal and vibration during braking. - Environmentally Friendly
Asbestos-free composition aligns with global safety standards, ensuring minimal health risks. - Customizable Formulations
The brake linings formula can be adjusted to meet specific OEM requirements, such as varying friction levels or compatibility with cast iron drums.
Storage and Packaging
- Moisture Protection: Sealed in moisture-resistant, neutral packaging to prevent oxidation .
- Temperature Control: Store in dry environments between -10°C and 40°C to avoid material degradation .
- Stacking Limits: Maximum 6 layers to prevent deformation of sintered linings .
- Shelf Life: 24 months in unopened original packaging .
Application of Brake Linings Mixes
Sintered brake linings mixes are manufactured through high-pressure compaction (20-50 MPa) and sintering at 800-1000°C, ensuring strong adhesion between the friction layer and backing plate. Post-production tests include shear strength (≥4.0 MPa) and thermal cycling validation to guarantee reliability .
For specialized applications, manufacturers may integrate graphite or ceramic particles into the brake linings mixture to enhance performance in extreme environments .
This sintered technology ensures unmatched durability and safety for commercial trucks operating in mountainous terrain or heavy-load logistics.
