Abstract

In this paper thermal and mechanical properties of elastic epoxy for applying high voltage products were investigated. Glass transition temperature(Tg) of elastic epoxies can't find form room temperature to $200^{\circ}$ by DSC. It occurred weight reduce on $285^{\circ}$ and $451^{\circ}$ by thermo-gravimeter. The first temperature was effected on addictives and the other was epoxy's character. Max, tensile strain showed $28.3kgf/cm^2$ at 20% of mechanical stress in addictives 35phr. SEM micrograph of the fracture surface observed in void and tearing of elastic epoxy at addictives 35phr. The other side, SEM micrograph of rigid epoxy showed the trace which broke.
