Extruded nib design for automotive floor mats

A floor mat comprising:

• a backing layer having a thickness of 0.5 mm to 6.0 mm and a surface wherein said backing layer is formed from a thermoset or a thermoplastic elastomer having an ash content in the range of 20 to 40% by weight, a melt index in the range of 60 to 150 as measured at 190° C. and 21.6 kg, a tensile strength in the range of 3000 kPa to 5,000 kPa, an elongation in the range of 450% to 700% and a density in the range of 1.0 g/cm3 to 1.33 g/cm3;
• and
• a plurality of nibs formed from the backing layer and integrally connected to said backing layer extending from the surface, wherein
• each of the nibs is tiered, including a frusto-conical base extending from the surface of the backing layer, said frusto-conical base having an upper surface and a tip extending from said upper surface of the frusto-conical base defining a height for said tip wherein said tip includes a sidewall that meets the upper surface of said frusto-conical base wherein said tip has a diameter and said frusto-conical base has a diameter and the diameter of said tip is less than the diameter of said frusto-conical base, the nibs having a maximum diameter in the range of 0.5 to 3.0 mm and an overall height in the range of 1.5 mm to 5 mm wherein said height of said tip is 10-50 percent of said overall nib height and wherein said tip has a distal portion extending from said frusto-conical base of said nib that is flat, and
• each nib is located within a column and a row and is offset from at least one other nib present in the column and at least one other nib present in the row and wherein said floor mat indicates a static coefficient of friction of greater than 2.0, on a non-woven or tufted testing surface, in both vertical and horizontal directions of said testing surface, when tested according to ASTM D1894-11.
