An expanded particle producing apparatus includes a vessel and a blade stirrer that is located inside the vessel. The blade stirrer comprises a stirrer base and an impeller blade that is attached to the stirrer base. A distance from the bottom of the vessel to the center of the stirrer base (L1) and a depth of the vessel (L2) have a ratio (L1/L2) of 0.01 to 0.2. L1 is measured in a depth direction parallel to L2, and a central axis of the blade stirrer coincides with a central axis of the vessel. The apparatus is configured to produce expanded particles.

Methods for processing polyolefin recyclates including, but not limited to, polyethylene and polypropylene and compositions therefrom are provided. polyolefin recyclate feedstocks can be visbroken to improve processing characteristics and/or devolatilized to remove waste byproducts to produce processed polyolefin recyclates. Processed polyolefin recyclates are compounded with pre-consumer polyolefins to produce blend compositions having acceptable or even improved processing characteristics. Such pre-consumer polyolefins can also be visbroken to further tailor processing characteristics of such polymer blends. A combination of extruders and/or extruder zones can be used at the same or different locations for visbreaking and/or compounding of both polyolefin recyclate and/or pre-consumer polyolefins.
