High speed train brake pad Powder-Metallurgy Speed:300-350km/h
High speed train brake pad Powder-Metallurgy Speed:300-350km/h
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.
