Abstract
This invention relates to a cushioned dust control mat or article wherein the mat comprises at least two distinct layers of rubber, one comprising foam rubber, the other comprising solid rubber and has a plurality of star-shaped protrusions in the upper surface thereof. Also, the surface of the mat between the protrusions is ribbed or recessed. The solid rubber layer is present over the foam rubber layer on the top side of the mat in which the plurality of star shaped rubber protrusions are present to provide cushioning characteristics. The solid rubber layer acts as a cap or barrier for the foam rubber layer, particularly over the star shaped protrusions, in order to provide a mat which is resilient, will not easily degrade in its modulus strength after appreciable use and/or washing within industrial cleaning processes, and will not exhibit appreciable cracking or breaking, particularly within the star-shaped protrusions, after standard use for pedestrian traffic. A method of producing such an inventive cushioned floor mat is also provided.
