Thermoplastic elastomer (TPSiV) based on polyurethane (TPU) and silicone rubber have been prepared through dynamic vulcanization using Haake torque rheometer. This article mainly studies the effect of the processing technology, crosslinking agent content, catalyst agent content and curing rate on the mechanical properties of the thermoplastic elastomer; discusses the phase inversion point under different blend ratio, dynamic vulcanization processing and polyurethane materials with different viscosity. The e...
