Introduction to Car Brake Pads with NAO (Non-Asbestos Organic) Formula
NAO brake pads utilize advanced brake pads mixtures composed of organic fibers, synthetic resins, and ceramic compounds, replacing hazardous asbestos with eco-friendly Brake Pads Friction Materials. This Brake Pads Formula ensures superior safety and compliance with global environmental regulations.

Advantages of NAO Formula
- Asbestos-Free & Eco-Safe
- The Brake Pads Mixes combine cellulose, aramid fibers, and ceramic particles, eliminating carcinogenic asbestos and complying with EU REACH/ROHS directives.
- Low Noise & Vibration
- Optimized brake pads friction materials reduce high-frequency squeal by 50% compared to semi-metallic formulas.
- Gentle Rotor Wear
- Softer organic compounds decrease rotor abrasion, extending rotor lifespan by 20–30%.
- Rapid Heat Dissipation
- Ceramic-enhanced brake pads formula maintains stable friction performance up to 500°C, preventing brake fade.
Storage & Packaging Guidelines
- Packaging:
- Vacuum-sealed in moisture-proof aluminum bags with desiccants.
- Outer cartons labeled with “Fragile” and “Keep Dry” warnings.
- Storage:
- Temperature: 5°C–30°C in UV-protected warehouses.
- Maximum stacking height: 4 layers to avoid deformation.
Key Formula Composition
The Brake Pads Mixture includes:
- Friction Modifiers: Graphite (10–12%), vermiculite (8–10%)
- Binders: Phenolic resin (15–18%)
- Reinforcements: Aramid fibers (20–25%), ceramic powder (12–15%)
This NAO brake pads formula is ideal for urban passenger vehicles prioritizing quiet operation and environmental sustainability.
