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.

Abstract: Foamed propylene-based reactor made polyolefins, and articles made therefrom, are described. The compositions have a resin that is a reactor made propylene based random copolymer or terpolymer with high comonomer content, combined with a foaming agent. The foaming agent can be at least one physical blowing agent or at least one chemical foaming agent, and may include optional nucleating agents. Reactor made copolymers and terpolymers have a large range of high comonomer content and therefore have physical properties such as increased flexibility, high gloss, lower sealing temperature, and improved compatibility with other polyolefins. These properties translate into a broad scope of potential applications and foamed architecture. This allows the combination of the copolymer or terpolymer, and foaming agents to be fine-tuned for selected foaming application.
