PROGRESS IN RUBBER PLASTICS AND RECYCLING TECHNOLOGY, 2025 (SCI-Expanded)
This study investigated the influence of varying amounts of fumed silica filler on phenyl vinyl methyl polysiloxane (PVMQ) elastomer properties. Results demonstrate a significant impact of silica filler quantity on hardening, mechanical strength, relaxation, and damping properties of PVMQ elastomers. Notably, 15 phr fumed silica positively affects scorch time and optimum cure times. Increasing silica filler levels enhances mechanical properties, including hardness, Emod, and 50% modulus, by reinforcing physical and chemical cross-linking. The unique surface morphology of silica fillers enhances mechanical performance and energy absorption capacity, as evidenced by tan delta values. Multi-cycle compression tests confirm increased deformation resistance and energy absorption damping capacities with higher silica filler content. Temperature scanning stress relaxation analysis reveals notable effects on thermal relaxation properties. These findings underscore the crucial role of silica filler quantity in shaping the mechanical, damping, and thermal relaxation properties of PVMQ-based materials, suggesting avenues for performance optimization through surface morphology manipulation.
