Polyester felt is a synthetic needle punched felt made from polyester fibers. Material is normally supplied either black or white. (See the anti-squeak/anti-rattle felt for Sutherlands’ full line of black polyester felt.)
This general purpose felt is made in various densities with thicknesses ranging from .019″ to 2″. Polyester felt is fairly inexpensive, and often made in comparable density and thickness to SAE pressed wool felt. The maximum temperature of polyester felt is 300 degree F., compared to 200 degrees for SAE pressed felts. This material is commonly used for filtration applications, gaskets, wipers, and padding in a wide variety of industries. The density of polyester felt is commonly measured in ounces/per Sq. yard. Sutherland can custom manufacture this material to virtually any density.
