At Bull Chemicals, Rock Wool Brake Pads are built on two core pillars: strict global compliance and strong adaptability to diverse conditions. With our expertise in friction materials, Rock Wool serves as the key to balancing performance, compliance, and versatility in every product.

First: Unwavering Compliance of Rock Wool Brake Pads
Compliance runs through our entire production, starting with Rock Wool—a core component of brake pads friction materials. It fully meets EU REACH and US FMVSS 105 standards, with restricted heavy metals kept ultra-low (lead ≤ 10ppm, mercury ≤ 1ppm, cadmium ≤ 2ppm). When integrated into our brake pads formula, it ensures the final product passes SAE J2784 tests, maintaining a stable friction coefficient (0.38-0.42) across 0-600℃. We also tailor brake pads mixture to regional standards like China’s GB 5763-2021 for seamless market access.
Second: Core Advantages of Rock Wool in Brake Pads Friction Materials
Rock Wool delivers unmatched value in brake pads friction materials. It has exceptional thermal stability—retaining 95% structure at 800℃, cutting brake fade by 30%. Its low thermal conductivity (0.04W/(m·K)) extends brake assembly lifespan by 25%. Additionally, its fibrous structure boosts homogeneity in brake pads mixes, reducing wear rate to 0.08g/1000 cycles (ISO 6310)—15% better than traditional mineral fibers.
Third: Strong Adaptability of Rock Wool Brake Pads Across Scenarios
Our Rock Wool Brake Pads adapt to all scenarios via customized brake pads mixes. For heavy-duty vehicles, we raise Rock Wool content to 22% (by weight) for 15-ton axle load braking. For high-performance cars, we lower it to 18% (blended with graphite) for quiet, responsive braking at 120-180km/h. Even in extreme environments (-40℃ to 50℃), the brake pads mixture stays consistent—initial braking force deviation <5% at -30℃, and 10,000+ maintenance-free km in coastal areas.
Bull Chemicals leverages Rock Wool to create Brake Pads that unify compliance, durability, and adaptability. Our tailored brake pads formula and Rock Wool expertise will support your product success, whether for global standards or niche needs.
