Silicone elastomer has various properties such as heat-chemical resistance, electrical insulation, abundant elasticity and softness. The two component polymerized (RTP-2) silicon is composed of reactive oil polymer and mostly Pt catalyst. Base on this RTP-2 silicone elastomer, its mechanical and dielectric properties are widely studied with different mixing ratio. Basically, the degree of polymerization could be controlled by the ratio of crossslinker and its catalyst so that the mixing ratio between resin and curing agent is important to optimize polymer properties. As a result, the optimized shore hardness, elongation length and Young’s modulus were carried out by using UTM, Durometer. Furthermore, its viscosity change and pot life during polymerization was also studied with rheometer by time scale experiment. For the application, the multilayered silicones were fabricated and measured its mechanical behavior compared with single layer to target medical surgery simulator. |
