Polyester felt is a synthetic needle punched felt made from polyester fibers. SFG supplies this felt in black, white or gray blends but can also provide various colors on special order. Polyester felt is made in various densities with thicknesses ranging from .020″ to 2″. We offer various densities but standard call-outs are soft, medium and hard densities. The maximum continuous operating temperature of polyester felt is 300° F. This material is commonly used for filtration applications, gaskets, wipers, and padding in a wide variety of industries. The polyester we use for our felt also can be dyed and printed as it takes inks well.
