Optimization of the mechanical performance of TDI-based polyurethanes via orthogonal design and response surface methodology

Year: 2025

Type: article

Abstract: -value, chain extension coefficient, and curing temperature was observed. Additionally, a volcano-shaped relationship was identified between tensile strength and the crosslinking coefficient, while a similar non-monotonic trend was found between elongation at break and curing temperature. Through multiple characterization experiments including equilibrium swelling measurements, differential scanning calorimetry (DSC) and scanning electron microscopy (SEM), the relationship between elastomer crosslink density and mechanical properties was systematically examined. This work provides valuable insights for the rational design of high-performance polymer materials.
