Graphite in Friction Applications: Brake Pads and More

1. Brake Pads and Linings

• Application: Graphite is a key ingredient in brake pads and brake linings, which are used in vehicles and industrial machinery.

  
  

Friction Modulation:

The inherent lubricity of flake graphite helps achieve a stable and optimal friction coefficient, ensuring consistent braking performance.

Thermal Management:

With excellent thermal conductivity, flake graphite efficiently dissipates heat generated during braking, reducing the risk of overheating and associated wear.

Noise Reduction:

The inclusion of flake graphite contributes to quieter braking by dampening vibrations and minimizing noise.

Enhanced Durability: Its high-temperature resistance and chemical stability protect brake pads from degradation, extending their service life.

• Common Grades and Specifications:

  
  

• The selection of flake graphite for brake pads depends on specific performance requirements. Manufacturers offer various grades with differing carbon content and particle sizes. For instance, high-purity natural flake graphite with carbon content ranging from 94% to 99.99% and particle sizes from -100 mesh to -325 mesh is commonly used.

  
  

• Incorporating the appropriate grade of flake graphite into brake pad formulations ensures optimal performance, safety, and longevity of braking systems.
