Eco-Friendly MgO Boosts Brake Performance

Carboleg GmbH, a leading supplier of synthetic graphite and carbons, has developed a groundbreaking sustainable magnesium oxide (MgO) product specifically designed for brake pad applications. This innovative material not only enhances the mechanical performance of brake pads but also aligns with environmental sustainability and cost-efficiency objectives.

Key Highlights

Enhanced Mechanical Strength: Notable improvements in shear and tensile strength.
Consistent Friction Performance: Matches standard formulations across various test conditions.
Reduced Wear: Lower wear rates for both brake pads and rotors, extending service life.
Environmental Benefits: 98% reduction in CO2 footprint and no heavy metals.
Cost-Effective: Provides a budget-friendly alternative to traditional virgin MgO.

Proven Performance in Real-World Applications

In a recent trial, Carboleg tested its Sustainable MgO as a direct replacement for standard virgin MgO in a copper-free, low-steel brake pad formulation widely used in European and American markets. The formulation incorporated 10% MgO and 8% synthetic graphite, both substituted with Carboleg’s proprietary products. The results demonstrated significant advancements: brake pads showed improved shear and tensile strength, ensuring durability, while friction performance remained consistent with existing standards. Thermal testing under dynamic conditions (0.5 N/mm², 15 m/s) from 150°C to 350°C confirmed the material’s stability. Additionally, the product reduced wear on both pads and rotors, promising longer service life and lower maintenance costs.

A Step Towards Sustainable Manufacturing

Carboleg’s Sustainable MgO stands out for its environmental benefits. It boasts a 98% lower CO2 footprint compared to virgin MgO, making it an ideal choice for manufacturers targeting sustainability goals. With no heavy metals, it supports cleaner supply chains, aligning with industry trends and stringent regulations.

Industry Impact and Vision

Leonid Enov of Carboleg emphasized, “Our sustainable magnesium oxide is more than a green replacement — it’s a performance booster. We’re helping manufacturers meet evolving environmental regulations while improving the reliability of their products.”

Invitation to Industry Leaders

Carboleg is seeking partnerships with leading OEMs and Tier-1 suppliers to integrate this innovation into broader production.
