Abstract: Embodiments of the present disclosure are directed to polymer blends comprising thermoplastic elastomer and 4 wt % to 50 wt % of cross-linked silane grafted polyolefin. The thermoplastic elastomer comprises a Shore A hardness from 0 to 80 as measured in accordance with ASTM D2240 and a compression set greater than or equal to 80% as measured in accordance with ASTM D395 at 125 C. The cross-linked silane grafted polyolefin comprises a compression set less than or equal to 70% as measured in accordance with ASTM D395 at 125 C.
