Carpet, carpet backings and methods

A carpet structure comprising:

• a) a primary backing material with a face and a back side;
• b) yarn tufted into the primary backing so as to produce a carpet pile on the face side of the primary backing and loops of yarn on the back side of the primary backing;
• c) a first polymer layer comprising at least one homogeneously branched ethylene polymer characterized as having a short chain branching distribution index (SCBDI) of greater than or equal to 50 percent;
• d) a reinforcing material adjacent to the first polymer layer;
• and
• e) a second polymer layer comprising at least one homogeneously branched ethylene polymer characterized as having a short chain branching distribution index (SCBDI) of greater than or equal to 50 percent,
• wherein either or both of the first or second polymer layers comprises at least one adhesive polymeric additive, wherein the first polymer layer comprises a higher melt index than the second polymer layer, wherein an inorganic filler material is included in the polymer layers in an amount between about 15 weight % and about 60 weight % of the total composition, wherein the first polymer has a lower filler content, and the second polymer has a higher filler content, and wherein the reinforcing material is between the first and second polymer layers, wherein the carpet structure is suitable for cutting to provide dimensionally stable carpet tiles and wherein the carpet structure does not have a polyurethane foam laminated to a back side of the carpet structure.
