【Abstract】 The global concern for environmental protection and green development continues climbing. Biomass extrusion foaming composites as environmentally friendly materials have attracted much attention. Biomass and thermoplastic polymers as raw materials are renewable and recyclable, and the application properties of the product can be optimized through appropriate processes and additives, so it is a new type of material for sustainable development. This paper introduces the impact of the extrusion foaming process on the performance and application of composites, focusing on comparison of the advantages and disadvantages of the molding equipment, including single-screw extruder, and twin-screw extrusion, and summarizes the composition of extrusion foaming formulations, that is, the addition of blowing agents, nucleating agents, plasticizers, cross-linking agents, etc. The optimization of the material properties, and the application of biomass-extruded foaming composites in the packaging and construction industries are reviewed in detail.更多还原
