The report focuses on one of the implementation solutions for lightweight and high-performance new energy vehicle components - microcellular foaming. It introduces microcellular foaming materials and their innovative processes from two categories: supercritical fluid foaming and subcritical fluid foaming, emphasizing the need to obtain the required product performance from the perspective of cell structure control. It reveals that forming differentiated micropores can meet various needs of materials and products for new energy vehicle components, such as lightweight, high strength, thermal insulation, impact resistance, sound insulation (or absorption), and shock resistance.
In its relentless pursuit of excellence, the new energy vehicle industry is constantly seeking innovative solutions to improve performance while reducing costs and environmental impact. Nouryon Expancel® microspheres are a cutting-edge additive that can be used in the new energy vehicle industry. Expancel® microspheres are small spherical particles. The microspheres consist of a polymer shell encapsulating a gas. When heated, the internal pressure from the gas increases and the thermoplastic shell softens, resulting in a dramatic increase of the volume of the microspheres. The gas remains inside the spheres. Expancel® microspheres are foaming agent, and lightweight filler, all in one.
