Key Advantages
- Eco-Safe Composition
- The Brake Shoes Mixes combine ceramic fibers, steel wool, and aramid pulp, eliminating asbestos-related health risks.
- Enhanced Thermal Stability
- Stable friction coefficient across temperature ranges (-30°C to 550°C), reducing brake fade during prolonged use.
- Low Noise & Vibration
- Optimized brake shoes friction materials minimize high-frequency noise (<65 dB at 80 km/h braking).
- Corrosion Resistance
- Non-hygroscopic formula prevents moisture absorption, extending service life by 25% compared to traditional asbestos shoes.
Storage & Packaging Guidelines
- Packaging:
- Individually wrapped in anti-oxidation film.
- Stacked in reinforced cartons with desiccant packets (max 50% humidity).
- Storage:
- Temperature: 5°C–30°C in dry, UV-protected environments.
- Avoid vertical stacking beyond 8 layers to prevent deformation.
Formula Composition
The brake shoes formula comprises:
- Friction Modifiers: Graphite (10–12%), barium sulfate (8–10%)
- Binders: Modified phenolic resin (12–15%)
- Reinforcements: Ceramic fibers (20–25%), aramid pulp (5–8%)
- Fillers: Vermiculite (10–12%)
This Brake Shoes Mixture ensures compliance with EU Regulation (EC) No 1907/2006 (REACH) and meets OEM performance benchmarks.
