The proportion of MDI influence the embrittlement performance of TPU at low temperatures
Nov 03 , 2023
MDI is one of the key components used in the production of TPUs. It serves as the isocyanate component, reacting with polyols to form the polyurethane segments of TPU. The selection of MDI type and the ratio of MDI to polyols can affect the physical properties and performance characteristics of the TPU, including its low-temperature behavior. TPU formulated with a higher proportion of MDI generall...
