Non-asbestos organic type brake materials mainly use glass fiber

Non-asbestos organic type brake materials mainly use glass fiber, aromatic poly cool fiber or other fibers (carbon, ceramics, etc.) as a reinforcing material, and its performance mainly depends on the type of fiber and other additive mixtures.

Non-asbestos organic brake materials were developed primarily as alternatives to asbestos for brake drums or brake shoes, but they are also beginning to be used as a replacement for front disc brake pads. In terms of performance, NAO brake pads are closer to asbestos brake pads than semi-metallic brake pads. It does not have good thermal conductivity and good high temperature controllability like semi-metallic brake pads.

What is the difference between the new NAO raw materials and asbestos brake pads? Typical asbestos-based friction materials contain five to seven base blends, including asbestos fibers for reinforcement, a variety of additives, and binders such as linseed oil, resins, benzoquinone, and resins.
