Hello everyone, I’m from Annat. Today, let’s clarify what Calcined Petroleum Coke (CPC) is and its vital role in Brake Pads Mixes.

Brake Pads Calcined Petroleum Coke
First, CPC is a high-purity carbon material derived from raw petroleum coke through calcination at 1200-1450°C. This process removes volatile components, sulfur, and moisture, resulting in a product with core technical properties: carbon content ≥98%, sulfur content ≤0.5%, true density 2.0-2.15 g/cm³, and particle size customizable from 5μm to 200μm—tailored for Brake Pads Formula.
In brake pads manufacturing, CPC offers three key advantages backed by performance data.
1. Superior Friction Stability: Its porous structure creates a consistent friction interface. Tests show brake pads with 8-15% CPC maintain a friction coefficient of 0.35-0.45 across temperatures from -30°C to 350°C, with variation ≤15%. This avoids “friction fade” at high temps or “stick-slip” in cold conditions.

2. Exceptional Wear Resistance: The high hardness (Mohs hardness 2.5-3.0) of calcined coke reduces material loss. Under standard braking loads (1500N), pads containing CPC exhibit a wear rate of ≤0.8 cm³/(MJ), extending service life by 20-30% compared to those using conventional carbon fillers.
3. Cost-Effective Performance: Compared to graphite or carbon fiber, CPC delivers 90% of their friction performance at 40-60% of the cost. Its low ash content (≤0.3%) also minimizes brake rotor wear, lowering overall maintenance costs for end-users.
