G/D train brake pad Powder-Metallurgy Speed:200-250km/h
G/D trian brake pad Powder-Metallurgy Speed:200-250km/h
Independent intellectual property rights, research and development of the material powder metallurgy brake pads high-performance materials to ensure the strength of the matrix at same time to improve the thermal conductivity for the brake pads and different speeds of high enough friction coefficient and stability
Now train brake pad is application for Beijing railways and Train,Tianjin train,Shenzhen and so on many train lines.
Train brake pad a high-performance friction material. Using nitrile rubber and styrene-butadiene rubber as the matrix adhesive, and low carbon steel fiber, carbon fiber, precipitated barium sulfate and other powder raw materials mixed, by mixing, crushing, room temperature compression molding, curing and subsequent treatment process, The friction material is bonded to the metal dovetail plate and then connected to the vehicle’s dovetail trough through the metal dovetail plate. The recommended friction material is cast iron brake disc (such as dyed iron plate, etc.). This product does not contain substances such as asbestos and other UIC standards prohibited.
