The Effect of Addition of Coal Fly Ash as Filler in Silicone Rubber Polymer Isolator Materials on the Characteristics of Tensile Strength and Elongation

Fly ash is the remainder of the results of burning classified coal as B3 waste (material Poisonous and Dangerous). Enhancement use of coal as a material burn generator Keeps increasing the year, which enhances the magnitude of waste produced. In research, This utilization of ash coal as a material polymer insulator mixture of rubber silicone. The resulting mixed insulator was Then tested with testing strength tension and elongation. From the results study adding fly ash filler to the rubber insulator silicone can increase strength tensile strength, at a thickness of 2mm pull increase by giving 10% to 40% filler, at a thickness of 3mm strength pull increase with giving 10% to 30% filler but adding more filler carry on strength pull will decrease. The addition of coal fly ash filler to the polymer insulator material rubber silicone is influential to elongation, with Add value of coal fly ash filler its elongation the more decreases.
