Abstract

Ethylene Propylene Diene Monomer (EPDM) electrical properties are improved by adding Alumina Trihydrate (ATH) filler. Composite of EPDM with ATH filler are prepared with 10%, 20%, 30% and 40% percentages of concentration. The dielectric strength of the composite samples are tested under various thermal conditions such as (25, 70,100 and 130) ᵒC to simulate the various types of climates and clarify the effect of high temperature on the electrical properties of elastomers. Composite samples were exposed also to different climate conditions such as wet and salt. The obtained results of the composite performance are analyzed and discussed in the light of the variations of the material microscopic structure.
