Ethylene-propylene-diene terpolymer vulcanizates´ reinforcement with precipitated silica

Physical properties of rubber composites can be enhanced by employing the particulate fillers for example calcium carbonate, silica and carbon black. Modulus, tear & abrasion resistance usually have a tendency to increase by the incorporation of the fillers in elastomers. Particulate fillers like high-structured silica and carbon black, generally, offered considerable reinforcing effects. The key purpose of this paper is to study the impact of filler (Vulkasil C, precipitated silica) dosages/loading on the mechanical properties of interest for instance hardness, elongation at break, tensile strength and bound rubber of EPDM based rubber vulcanizates.
