Abstract

Silicone rubber (SiR) and Ethylene Propylene Diene Monomer (EPDM) rubber blends have been widely selected for high voltage (HV) insulating applications. The advantages shown through this combination are such as improving the mechanical properties of the insulator with much higher thermal stability and resistance to high voltages. SiR / EPDM rubber blends also provide lightweight properties, improving electrical properties and flexural strength. This research was conducted to prepare and evaluate the characteristics and performance of SiR / EPDM rubber composite blends reinforced with glass waste powder filler. The filler is derived from glass residue as a source of SiO2. Approximately 0, 10, 20, 30 and 40% by weight of glass silica waste powder were added into the SiR / EPDM rubber complaint formulation for the manufacture of SiR / EPDM- SiO2 composites. The effect of the addition of such fillers is evaluated from the aspect of their mechanical and physical performance. This finding, proves the potential of silica glass waste as a useful functional filler when test results identify XRD, PSA and SEM raw materials show the true properties of amorphous glass with size range 60-90 μm and elongated and angular shape that facilitates it to be SiR / EPDM for exceptional HV applications. SiR/EPDM blends with glass waste at 30% showed the most positive effect when the main tensile strength and elongation results proved to be the best composition with values of 6.2MPa and 531.5%. This clearly shows that glass waste is the best combination for SiR/EPDM rubber blends as high voltage insulator.
