Description

The physicomechanical properties and swelling of vulcanizates were studied by means of radiation vulcanization. The test samples were preheated and formed by a press at 154 deg C for 3 min. Irradiation was performed in atmosphere on 60Co (dosage 0.48 Mrad/hr). Irradiation caused decrease in tensile strength, as well as relative and permanent elongation; at the same time it considerably strengthened rubber hardness. All the rubber samples showed greater strength after irradiation under 5.7-13.8 Mrad. Depending on the dosage (3.6-13.8 Mrad), the relative and permanent elongation of vulcanizates obtained with the aid of altax was found to decrease, while strength and swelling increased. The swelling of rubber samples obtained with thiurad and thiuradaltax compounds decreased. Hence the advisability of using that rubber for manufacture of petroleum-resistant products
