A method of producing a thermoplastic polyurethane (TPU) compound including a polyurethane powder comprising microcellular polyurethane (MCU). The method minimizes discarding scrap MCU, reduces the cost of TPU articles by introducing a partial replacement for the TPU resin, and reduces injection-molding times to produce TPU articles. The TPU compound including polyurethane powder has superior melt temperature and compression set properties as compared to TPU compounds of similar Shore hardness that are free of the polyurethane powder. The invention also provides a TPU article including the TPU compound and a method of recycling a MCU foam. |
