Polyurethane damping material
Source abstract
Abstract
The mechanical and damping properties of thermoplastic polyurethanes (TPUs) prepared by polyether–aromatic polyester polyols were studied. Dynamic viscoelastic properties ( E′ and tan δ) were mainly investigated using a dynamical mechanical analysis. By increasing the content of the aromatic ester component of soft segment in each segmented PU, the value of tan δ increased, and the width of the peak narrowed with the same hard segment contents. It was desired that interaction between hard and soft segment in U-Fine (UF)-A and UF-B is uniform, and the degree of phase separation between hard and soft segment in UF-A and UF-B advanced in comparison with TPU-A. Tensile strength and abrasion resistance of UF-B (ester component content of polyether–ester polyol = 20.3 mol%) showed superior data compared with other commercial damping materials.
