Abstract: The invention relates to a compressor wheel for a high-speed compressor composed of a polymer material, having a wheel front side (6), a wheel rear side (11) and a wheel hub (3), wherein the wheel front side (6) has a curvature, by virtue of which the distance between a plane extending radially through the outer circumference (15) of the wheel front side (6) and the surface of the wheel front side (6) increases from the outer circumference (15) toward the wheel hub (3), and guide vanes (7) are arranged on the wheel front side (6). The wheel hub (3) projects in an axial direction on the wheel rear side (11), and reinforcing ribs (13) extend from the wheel hub (3) toward the outer circumference (15), wherein the distance between a plane extending radially through the outer circumference (15) of the wheel rear side (11) and the trailing edge (19) of the reinforcing ribs (13) increases from the outer circumference (15) of the wheel rear side (11) toward the wheel hub (3).The invention furthermore relates to the use of the compressor wheel.
