Friction Materials

United Material Brake Pads division is a pioneer in the design, development and manufacture of complete braking systems and when it comes to brake pads, the most important part is the friction material. Our development laboratories have been designing and testing materials to exceed the high quality expectations for wide range of vehicles and as a result, our brake pads performed significantly higher than original equipment service (OES) brake pads in independent tests. In fact, all United Material pads are engineered and improved beyond OE specifications.

     Company Products:

A. Semi-metal Brake Pad

The formula usually contains about 30%-45% iron metal, such as steel fiber, reduced iron powder or froth powdered iron. The material has the advantages of excellent heat stability and thermal conductivity. It overcomes the shortcomings of asbestos friction materials, such as serious heat recession and frictional interface easy to crack.

B. NAO (Non-asbestos) Brake Pad

Non-asbestos organic friction materials use a modified high temperature resin and rubber as adhesives, mix fiber reinforced materials with increased friction agent and antifriction agents, and then model or hot press or solidify. It is an environmental protection brake pad, because it uses other fibers instead of asbestos.

C. Powder Metallurgy Frictional Material

Powder metallurgy friction materials (that is sintered friction material) are that we mix iron-base, copper-based powder materials together, then model and sinter. It can avoid heat recession and heat wear under high temperature. And it is suitable for overloading and high-speed situation.
