Excessive brake pad wear and short service life are common issues during vehicle maintenance, which not only increase maintenance costs for car owners but also affect the market reputation of brake pad products. Especially in urban congestion with frequent stop-and-go driving and continuous braking on mountain roads, the wear rate of brake pads accelerates significantly. Most conventional brake pad formulations struggle to balance wear resistance while ensuring braking responsiveness, presenting a difficult performance trade-off. As a functional filler, magnesium oxide from Messi Biology can effectively improve the wear resistance of brake pads and extend their service life.
Magnesium oxide is evenly distributed and filled within the gaps between the fibers and the resin matrix of the brake pad. This effectively enhances the overall compactness and structural strength of the friction material, thereby increasing the matrix’s resistance to shear and wear. Under continuous friction operating conditions, magnesium oxide particles help share the mechanical stress at the friction interface, reducing the direct wear and peeling of the resin and fiber matrix, lowering the overall wear rate of the material, and effectively delaying the consumption rate of the brake pad.
At the same time, magnesium oxide stabilizes the transfer film at the friction interface, allowing friction losses to maintain a uniform, smooth, and micro-wear state while preventing abnormal wear phenomena such as localized rapid wear, groove wear, and flaky spalling. Conventional brake pads are prone to surface embrittlement, chipping, and uneven wear during long-term use. After the addition of magnesium oxide, the matrix toughness is significantly improved, the wear pattern becomes more stable, and the overall service life is noticeably extended.
Unlike high-hardness abrasive fillers, magnesium oxide has a moderate hardness. While enhancing the wear resistance of the brake pads, it does not accelerate the wear of the brake rotors, thereby achieving a two-way wear optimization for both the friction pad and the counterface rotor, and reducing the maintenance cost of the vehicle’s braking system. Messi Biology can customize magnesium oxide products with suitable particle sizes and purities according to different brake pad formulation systems, helping brake pad enterprises create high-wear-resistance, long-life, and high-cost-performance braking products.
