At Annat, we leverage Rock Wool as a high-performance reinforcing and heat-insulating component in Brake Pads Formula and Brake Pads Mixture, a choice driven by its unique ability to enhance safety, durability, and thermal stability—key pillars of reliable braking systems.

Brake Pads Rock Wool
Rock Wool, a mineral fiber derived from molten rock (basalt or diabase) processed at ultra-high temperatures, addresses two critical brake pad challenges: heat management and structural reinforcement. Technically, our selected Rock Wool grade features a fiber diameter of 4-7 μm and a length of 3-8 mm—dimensions optimized to interlock with other pad materials (like resins and friction modifiers), boosting overall structural integrity without compromising friction performance. Crucially, it boasts an excellent thermal resistance, with a continuous operating temperature range of -260°C to 760°C and a melting point exceeding 1,000°C—far above the peak temperatures (typically 400-600°C) generated during heavy braking, preventing thermal degradation of the pad’s internal structure.
Brake Lining Rock Wool
Its advantages extend beyond heat resilience. Rock Wool contributes to stable friction coefficient retention (maintaining a coefficient of 0.35-0.45 even under cyclic temperature fluctuations), ensuring consistent braking force and avoiding “brake fade”—a common risk with less heat-resistant materials. Additionally, it exhibits low moisture absorption (≤0.5% by weight after 24 hours of water immersion), preventing pad swelling or rusting that could shorten service life. In durability tests, Annat’s Rock Wool-infused brake pads show a wear rate reduction of 15-20% compared to standard formulations, translating to longer replacement intervals for end-users.
Car Brake Pads Anit Wear Formula
For Annat, Rock Wool is more than an additive—it’s a commitment to engineering brake pads that perform under pressure. Whether for passenger vehicles, SUVs, or light trucks, our Rock Wool-enhanced solutions deliver the thermal stability and longevity that drivers and manufacturers trust.
