文摘

The composition and properties of silicone–hollow microsphere composites were studied in view of establishing a new type of maxillofacial prosthesis material. Two types of microspheres were used in different concentrations and were well dispersed in the silicone matrix. The mechanical properties of the composites were evaluated. Expancel hollow microspheres improve the density, Shore A hardness, and breaking elongation of the materials but degrade their tensile strength, tear strength, and dynamic mechanical properties, while opposite trends were observed with hollow SiO2 microspheres. Ideal properties for maxillofacial prosthetic applications can thereby be obtained by blending the two types of hollow microspheres in specific proportions.
