Improving Properties of Dynamic Vulcanized Polyurethane and Silicone Rubber Elastomer through Controlling Interphase Layer
ABSTRACT In this work, a new kind of compatibilizer was prepared through the reaction between hyperbranched polyurethane and isocyanate-modified silicone oil and its application in the dynamic vulcanized polyurethane and silicone rubber elastomer was investigated. Compared with that of dynamic vulcanized thermoplastic polyurethane (TPU)/silicone rubber elastomer without compatibilizer, the introduction of 3% silicone-modified hyperbranched polyurethane lead to the increase in tensile strength from 8.1 to 13.9 MPa and the tear strength from 56.2 to 75.2 kN/m. The introduction of silicone-modified hyperbranched polyurethane as an interphase layer controller leads to the improvement in properties of TPU/silicone rubber elastomer. GRAPHICAL ABSTRACT
