Below is a list of Friction Materials manufacturers from Philadelphia, Pennsylvania. Friction materials are used in most industries to induce resistance in several applications that require slow or decreased movement, such as in brake and clutch systems. For example, industrial machinery, automotive equipment, operating systems etc. all require the ability to slow down and/or stop their processes.
