Low-density thermoplastic aliphatic foam board is a high-performance closed-cell foamed material produced by advanced clean supercritical fluid foaming technology. It boasts ultra-low density, outstanding ball resilience (up to over 80%), excellent anti-yellowing performance and low compression set, with stable tensile and tear strength. With a recommended maximum working temperature of 65℃, it maintains reliable performance under various conditions and is widely used in high-end footwear midsoles/insoles, sports equipment buffer parts, automotive interior components and other scenarios, perfectly meeting lightweight and high-performance application requirements.
What is advanced clean supercritical fluid foaming technology?
Advanced clean supercritical fluid foaming technology is an eco-friendly and high-precision foaming process for manufacturing microcellular porous foam materials, which uses supercritical fluid as the foaming agent and applies it to various thermoplastic elastomer substrates such as TPU, ATPU, TPEE and PEBAX; the whole production process is clean and pollution-free without harmful additives, and it can form a large number of uniform and fine micron-sized bubbles inside the polymer matrix through precise control of process parameters, which effectively optimizes the material’s internal structure and endows the prepared foam boards with the excellent comprehensive properties of low density, high mechanical strength, outstanding resilience and low compression set, and is the core technology for producing high-performance thermoplastic elastomer foam materials for footwear, auto parts, sports equipment and other fields.
