Effect of Electron Beam Irradiation Cross-Linking on Polyolefin/Phenyl Silicon Rubber Composite

The effect of polyolefin/phenyl silicon rubber composite with different proportion were investigated before and after irradiation cross-linking treatment, The changes in the properties such as tensile strength and elongation at break were monitored. A correlation between the mechanical properties and irradiation doses has been explained on the basis of INSTRON strength tester and XN-1 spandex elastic tester studies. The optimum radiation dose was found to be dependent on blend composition and morphology, however, an absorbed dose of 150KGy to 200 KGy were found to be effective enough to ensure good mechanical properties of the polyolefin/ phenyl silicone rubber composite.
