Soft Rubber Linings Based On Ethylene Propylene Diene and its B lend With Natural and Synthetic Rubbers

All studies on minerals stated that some of the earth’s raw material resources will soon be exhausted. This leads escapable to the conclusion that science and technology will have to devote more attention that they have done in the past to the protection and conservation of metals especially iron and steel. Rubber lining has been used for severe corrosion protection because; natural and synthetic rubbers have a basic resistance to very corrosive chemicals particularly acids and bases, and rubber materials are both flexible and stretchable. There fore, in this work the following materials were chose; 1- EPDM alone 2- EPDM blended with NR and / or SBR, to formulation soft rubber. The vulcanization processes were studied widely together with ingredients. Physico – mechanical and physico – chemical properties were thoroughly studied. an‎d the results show that the optimum value of physico – mechanical properties in using blend of EPDM / SBR / NR (70/15 /15) Phr, and EPDM vulcanized alone gave formulation with good resistance to chemicals.
