PROBLEM TO BE SOLVED: To provide thermoplastic elastomer compositions including at least one elastomeric component and at least one semi-crystalline polymer to replace PVC-based profiles, and articles made of the compositions.SOLUTION: A composition comprises: i) an ethylene/α-olefin interpolymer which has a Mooney Viscosity (ML 1+4, 125°C) greater than or equal to 55 and a &Dgr;Hf greater than or equal to 36 J/g; and ii) a high density polyethylene (HDPE), at least one oil, and at least one filler. The composition has a compression set less than 70% at 70°C as measured by ASTM D-395. |
