MODIFICATION OF SILICONE RUBBER BY ADDED PMMA AND NATURAL NANOPARTICLE USED FOR MAXILLOFACIAL PROSTHESIS APPLICATIONS

As a result of the increased incidence cases for a maxillofacial due to accidents and cases of disease has become necessary to work on the production of alternative materials for sites damaged in this area. The particularly important bio material is silicone rubber, which is widely used in damaged maxillofacial affected areas replacement surgery. The aim of this research, prepared a nano composites materials, from polymer blend (silicone rubber: 5% PMMA) reinforced by two different type of natural nano-powders. Pomegranate Peels Powder (PPP) and Seeds powder of dates Ajwa (SPDA) with loading level (0.0, 0.1%, 0.2%, 0.3% and 0.4%). Some mechanical properties such as tensile, hardness, compression and surface roughness were test, as well as, FTIR, DSC and SEM tests were done on prepared sample. The results showed that the optimum percent of both Pomegranate Peels Powder (PPP) and Seeds powder of dates Ajwa are 0.2%, 0.3 respectively that have ideal characteristic.
