Abstract: Foamed reactor made thermoplastic polyolefins (rTPOs), and articles made therefrom, are described. The compositions have an rTPO combined with a foaming agent. The foaming agent can be a physical blowing agent and/or a chemical foaming agent, and may include optional nucleating agents. Some compositions utilize a masterbatch having one or more chemical foaming agents to foam the rTPOs. The rTPOs have a large melt flow rate range and flexural modulus range that translate into a broad scope of potential applications and foamed architecture. This allows the combination of rTPOs and foaming agents to be fine-tuned for selected foaming application.
