Abstract
A filter element for removing particles from a particulate laden fluid stream includes, in an exemplary embodiment, a filtration media formed into a tubular configuration and that a plurality of circumferentially spaced apart pleats. The filter element also includes at least one melt-extruded retention strap extending circumferentially around the filtration media to limit radial movement of the filtration media at operating temperatures up to about 500° F. Each melt-extruded retention strap is formed from a melt extrudable amorphous thermoplastic polyimide.
