Introduction to Hydrolysis Resistance Parameters of TPU Materials

refers to its ability to resist “attack” by moisture and prevent performance degradation. This capability is determined by the chemical structure and additives of TPU, and is a key indicator for evaluating its long-term reliability in humid or underwater environments. Decisive Factor: Polyester-based vs. The fundamental difference in hydrolysis resistance comes from the “soft segment” structure within the molecular chain. Polyester-based TPU: The ester bonds in the molecu
