At Bull Chemicals, we know consistent braking starts with stable brake pad friction coefficients—and Rubber Antioxidant is key to this stability. Let’s break down its role, advantages, and data-backed impact.

First: Rubber Antioxidant’s Role in Brake Pad Friction Materials
brake pads friction materials need a balanced mix of fibers, binders, and fillers for reliable friction.brake pads Rubber Antioxidant protects the rubber-based binders here: it stops heat and mechanical stress from oxidizing binders, which would break them down and ruin friction consistency. Without it, brake pad mixes degrade fast, causing unpredictable friction coefficient swings.
Second: Advantages in Brake Pad Mixtures
Adding Rubber Antioxidant to brake pads mixture brings three unbeatable benefits:
1. It extends friction stability—keeping coefficients (industry standard 0.35–0.45) steady even after 500+ braking cycles, vs a 15–20% drop in mixes without it.
2. It boosts thermal resistance—keeping brake pad formulas stable up to 350°C, avoiding “fade” (sudden friction loss) that risks braking failure.
3. It improves durability—brake pads with our Rubber Antioxidant have 25% less wear over 30,000 km, cutting replacement needs for users.
Third: Data-Backed Impact on Friction Stability
Our lab tests prove Rubber Antioxidant’s value:
• Brake pads with 1.2% Rubber Antioxidant in their formula kept a friction coefficient of 0.40 ± 0.02 across 1,000 braking events.
• By contrast, the same brake pad mixes without it saw coefficients drop 19%—from 0.42 to 0.34—after just 600 cycles.
This data shows Rubber Antioxidant isn’t just an additive—it’s a must for consistent, safe braking.
For Bull Chemicals, Rubber Antioxidant reflects our commitment to safer, longer-lasting brake pads. We tailor its dosage to your specific brake pad formula, making sure you get optimal friction stability every time.
