A polymer blend suitable for use in automotive floor covering applications includes 100 parts by weight of a radial block copolymer having the general formula (AB)nBA, wherein n is greater than 1, each block A is a monoalkenyl arene polymer block and each block B is an elastomeric conjugated diene polymer block; from about 5 to about 200 parts by weight of a mineral oil; and from about 5 to about 300 parts by weight of a 1-olefin polymer. The resulting polymer blend may be formed into sheet materials which are recyclable, and which may exhibit low gloss and excellent tactility similar to vulcanized rubber. Further, the polymer blends of this invention may exhibit excellent grain retention, abrasion resistance, heat stability, and ultraviolet light stability.
