This investigation presents novel thermoplastic elastomers (TPEs) based on poly(styrene-butadiene-styrene) (SBS) and ester-type polyurethane (TIPLI-EX) materials were prepared with varying compositions. A series of investigations were conducted on the relationships between mechanical properties, dynamic mechanical properties, anti-vibration and vibration isolator properties given, and the different compositions. The experimental results show incompatibilities between SBS and TPU-EX. SBS mechanical properties, dynamic mechanical properties, anti-vibration and vibration isolator properties are improved with an increase in the amount of TPU-EX, suggesting that the blending of SBS with TPU-EX was consistent with the compound rule. Based on the obtained results, the viscoelasticity of SBS materials, their capacity to isolate vibration, and their anti-vibration performance can be adjusted by controlling the proportion of TPU-EX.
