Specially processed pyrite powder is a professional raw material for friction formula modification in brake pad production. It optimizes friction matching, improves high-temperature braking performance, lowers abnormal noise, and extends the service life of brake pads. Suitable for semi-metallic, ceramic and composite brake pad formula production.
Overview
This natural pyrite powder is tailor-made for brake pad factory formula deployment. As an indispensable inorganic friction modifier, it can adjust friction stability at different temperatures, improve material compactness, and effectively solve problems such as high-temperature thermal decay, wear and brake squeal during use.

FAQ
Q1: What is the main modifying role of pyrite in the brake pad formula?
A1: It mainly regulates the coefficient of friction at high and low temperatures, enhances the high-temperature resistance and anti-attenuation capacity, and at the same time reduces noise and increases wear resistance.
Q2: Will the addition of pyrite affect the pressing and forming process of brake pads?
A2: The powder has good dispersibility, no lumps, and is highly compatible with resin and fiber raw materials, without affecting the conventional hot-pressing and curing production processes.
Q3: Which type of brake pad factory formula is suitable for use?
A3: Widely compatible with semi-metal, ceramic, and asbestos-free environmentally friendly brake pad formulas, it is a commonly used modified raw material by friction material manufacturers
