In this work we study the influence of different types of plasticizers on the mechanical properties of rubber blend mixtures before and after the ageing process. We have used Oleic acid as plasticizer. Reference samples were mixed with an oleic acid content of 1 part of the oleic acid to the 100 parts of rubber and 3 parts of the oleic acid to the 100 parts of rubber with weight percentages of the surfactant ETOXON 2, 4, 6, 8, 10, 20, 30 and basic mechanical properties such as tensile strength, Shore A hardness, ductility, moduli 100, 200, 300 have been measured. Measurements were performed 24 h after blend vulcanization and then 1 month after. We have studied the influence of plasticizers on the measured properties and the influence of ageing on the measured properties. All measured mechanical properties change with chemical composition except Shore A hardness.
