Main technical content: This technology uses TPO foaming microspheres, which are easy to obtain and low in cost. It features a simple process, low equipment investment, and overcomes the disadvantages of traditional chemical foaming and supercritical physical foaming processes, such as their complexity, high equipment investment, and difficulty in control. It uses a compounding machine to prepare foaming masterbatches, modifies and grafts foaming with a twin-screw extruder, and uses a series of mold hot-pressing forming processes. The resulting products have a density of 0.05-0.9 and excellent performance. They are environmentally friendly and do not damage the atmosphere. The products made are lightweight, with a specific gravity ranging from 0.5-0.9 g/cm3, and have the advantages of flexibility, good hand feel, and excellent resilience.
