Description

This microcellular TPU foam is produced using thermoplastic polyurethane (TPU) as its base composition, with clean supercritical carbon dioxide as the blowing agent. This process forms a uniform matrix of microcells, resulting in a material that is both lightweight and clean. It offers excellent cushioning performance, outstanding resilience, and high tensile strength. Key characteristics include exceptional low-temperature resistance, good chemical resistance, and full recyclability.
