At Bull Chemicals, brake pads Six Potassium Titanate Whisker stands out as a premium multifunctional additive in brake pads formula, going beyond basic reinforcement to elevate both performance and durability. Its core value lies in simultaneously enhancing friction stability, wear resistance, and noise reduction—three critical demands for modern brake systems.

Firstly, it delivers exceptional friction stability.
The unique needle-like structure of our whiskers (with an aspect ratio of 10:1 to 20:1) creates a rigid, heat-resistant framework within the friction matrix. This framework maintains structural integrity even at temperatures reaching 800°C, resulting in a consistent friction coefficient (μ) of 0.35 to 0.45 across the entire operating temperature range of 100°C to 650°C, effectively eliminating dangerous friction fade.
Secondly, it significantly boosts wear resistance.
The high hardness (Mohs hardness of 5.5 to 6) of six potassium titanate whisker acts as a load-bearing skeleton, reducing the abrasion of the brake pad surface. Testing data confirms that brake pads incorporating our whiskers achieve a specific wear rate as low as 1.0 x 10⁻⁷ cm³/(N·m), extending the service life of the brake pad by 30% compared to those using traditional fiber fillers.
Thirdly, it excels in noise and vibration dampening.
Unlike rigid fibers, the whiskers’ inherent flexibility allows them to absorb and dissipate the vibrational energy generated during braking. This capability reduces the occurrence of brake noise (NVH) by up to 15 decibels, significantly improving driving comfort without compromising braking efficiency.
Bull Chemicals’ six potassium titanate whisker is surface-treated with a special coupling agent, ensuring optimal dispersion and compatibility with phenolic resin binders and other friction components. This ensures that our customers can consistently produce high-performance brake pads with minimal production adjustments.
