At least one embodiment of this invention relates to a cushioned dust control
mat article wherein the mat comprises at least two distinct layers of rubber, one
comprising foam rubber, the other comprising solid rubber. The solid rubber layer
is present over the foam rubber layer on the side of the mat in which at least
one integrated rubber protrusion is present to provide cushioning characteristics.
The solid rubber layer acts as a cap or barrier for the foam rubber layer, particularly
over the integrated protrusion or 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 integrated protrusion(s), after standard
use for pedestrian traffic. A method of producing such an inventive cushioned floor
mat article is also provided.
