Abstract: An overmolded thermoplastic article includes a substrate portion molded from a thermoplastic resin compound and an overmold portion molded from a thermoplastic elastomer compound. The thermoplastic resin compound includes thermoplastic polymer resin. The thermoplastic elastomer compound includes thermoplastic elastomer and polysiloxane as a mold release agent, and is free of wax.
