brake pads Calcined Petroleum Coke , a cornerstone material supplied by Bull Chemicals, plays an irreplaceable role in high-performance brake pads formula. Its primary function is to serve as a critical friction modifier and thermal conductor, ensuring consistent braking performance under extreme conditions.

Firstly, CPC excels in thermal management.
With a high carbon content of 98.5% minimum and a low volatile matter of less than 0.5%, it efficiently dissipates the intense heat generated during braking—often exceeding 600°C. This prevents thermal degradation of organic binders and maintains stable friction coefficients, which typically range between 0.35 and 0.45 when CPC is incorporated at an optimal dosage of 8-12% by weight.
Secondly, it enhances wear resistance.
The rigid, graphitic structure of our CPC, characterized by a low ash content of less than 0.3%, acts as a durable matrix. This reduces both disc and pad wear rates by up to 20% compared to formulations using alternative carbonaceous materials, significantly extending the service life of the braking system.
Lastly, CPC contributes to noise and vibration damping.
Its porous yet strong structure helps to absorb and dampen the high-frequency vibrations that cause brake squeal, improving driving comfort without compromising braking efficiency.
At Bull Chemicals, our CPC is engineered to meet the stringent demands of the automotive industry, providing reliable and high-performance solutions for brake pad manufacturers worldwide.
