brake pads Acrylic Fiber is a foundational reinforcing component in brake pads mixture composite formulations, and Bull Chemicals, a specialist in advancing brake pads friction materials technology, recognizes its critical role in enhancing brake pad performance, safety, and durability. A typical brake pad is a composite system comprising binders (for structural cohesion), friction modifiers (for adjusting friction characteristics), and reinforcing fibers (for resisting stress-induced damage). Acrylic fiber stands out among reinforcing fibers due to its unique properties, delivering key benefits to brake pad performance.

First, Exceptional Thermal Stability
Brake pads reach up to 500°C during heavy braking. Brake pads acrylic fiber retains 90% tensile strength at 250°C and decomposes above 400°C, outperforming polyester fiber (loses 50% strength at 180°C). It maintains structural integrity to prevent brake pad breakdown.
Second, Consistent Friction Performance
Friction coefficient (μ) is vital for brake efficiency. Brake pads acrylic fiber’s uniform 12-18 μm diameter and 3-6 mm length form a balanced matrix. Brake pads with 8-12 wt% acrylic fiber keep μ stable at 0.38-0.42 over 10,000 cycles, while other fibers cause ±0.05 fluctuations, ensuring predictable braking.
Third, Enhanced Wear Resistance
Brake pads acrylic fiber cuts wear rate to 0.08-0.12 mm/1,000 cycles—30% lower than cellulose fiber (0.14-0.18 mm/1,000 cycles). With ≥600 MPa tensile strength, it acts as a “skeleton” to distribute stress and reduce material loss.
Fourth, Excellent Material Compatibility
It bonds well with phenolic resins (main binder) and additives like graphite. This cuts structural voids by 40%, minimizing braking noise and vibration.
Bull Chemicals optimizes acrylic fiber via a proprietary treatment, boosting fiber-matrix adhesion by 25%. Customizable in diameter, length, and surface treatment, it meets client-specific needs.
In conclusion, brake pads acrylic fiber is critical for brake pads to meet safety, durability, and reliability standards. Bull Chemicals’ solutions drive progress in brake pad material technology.
