Abstract: Thermoplastic elastomer compounds include (a) hydrogenated styrene-farnesene-styrene block copolymer, (b) thermoplastic polyester elastomer having a bio-based content of at least about 45%, (c) polyolefin having a bio-based content of at least about 95%, (d) secondary styrenic block copolymer such as styrene-ethylene/butylene-styrene block copolymer, and (e) plasticizer. The thermoplastic elastomer compounds have a bio-based content of at least about 40%. Additionally, the thermoplastic elastomer compounds have an adhesion of at least about 10 pli according to a 90° Peel Test on at least one of acrylonitrile butadiene styrene, polycarbonate/acrylonitrile butadiene styrene, and polycarbonate. The thermoplastic elastomer compounds can be especially useful for making overmolded thermoplastic articles.
