Comparison between mechanical properties of aged and unaged silicone rubbers filled with titanium dioxide,quartz,aluminium silicate and vulkasil (s type)
Silicone rubbers have advantageous thermal and electrical properties compared with other elastomers. Their mechanical properties, such as tensile strength and tear resistance are relatively weak compared with other elastomers. In this work, inorganic fillers such as titanium dioxide (TiO2) 2 and 5 phr, quartz, aluminium silicate and vulkasil (s type) 5, 15 and 25 phr were used in silicone rubber compound samples. Improvement in mechanical and processing properties are observed for these samples. The samples containing 2 phr TiO2 had a better tensile strength and transparency compared with those containing 5 phr TiO2. Determination of tensile strength, elongation at break, modulus, tear resistance, resilience and compression set of aged and unaged samples showed that higher values are obtained for samples containing quartz.
