Its high thermal conductivity aids in rapid heat dissipation, preventing brake fade and extending the lifespan of brake shoes friction materials. - Wear Resistance:
The layered structure acts as a solid lubricant, reducing abrasive wear between contact surfaces in Brake Shoes Ingredients. - Noise Reduction:
Minimizes squeal and vibration by dampening interfacial oscillations in the Brake Shoes Formula. - Oxidation Resistance:
Withstands oxidative degradation at elevated temperatures, maintaining structural integrity in harsh environments.
Storage and Packaging
To preserve the quality of Big Flake Graphite in brake shoes mixes:
- Storage:
- Store in a dry, cool (<30°C), and well-ventilated area.
- Avoid exposure to moisture, acids, or oxidizers to prevent contamination.
- Packaging:
- Typically supplied in multi-layered, moisture-resistant paper bags or sealed polyethylene-lined containers (25–50 kg/bag).
- Bulk packaging (1-ton super sacks) is available for industrial-scale applications.
Application in Brake Shoes
In brake shoes formulas, Big Flake Graphite is blended with resins, metal fibers, and ceramic additives to form a cohesive brake shoes mixture. Its role includes:
- Acting as a lubricant to stabilize friction coefficients.
