摘要

A new and improved contamination-control mat assembly (110) which has a plurality of adhesive-coated sheets (12) disposed upon the upper surface portion (114) of the contamination-control mat assembly, and a new and improved polystyrene frame member (112), having an acrylic-rubber anti-slip backing member (116) applied thereto, disposed upon the undersurface portion of the contamination-control mat assembly, wherein the polystyrene frame member (112) and the acrylic-rubber anti-slip backing member (116) are integrally affixed together by means of a co-extrusion process (200,216,214,218,212,220).
