Abstract: The present invention relates to thermoplastic elastomer compositions resistant to silicone oil. The thermoplastic elastomer compositions, hereinafter also called TPE compounds, moreover have Shore A hardness from 40 to 90 ShA and after storage in silicone oil exhibit very little change of mechanical properties such as hardness, elongation at break, and tensile strength, or of swelling behaviour. The thermoplastic elastomer compositions according to the invention moreover exhibit very good adhesion on thermoplastics such as polypropylenes (PP), polyethylenes (PE), polyamides (PA), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), acrylonitrile-butadiene-styrene polymers (ABS), polycarbonates (PC), acrylate-styrene-acrylonitrile polymers (ASA), styrene-acrylonitrile polymers (SAN), polyoxymethylenes (POM) and blends of these, for example PC-ABS blends (PC/ABS).
