Mechanical properties change of thermoplastic elastomer after using of different dosage of irradiation by beta rays

Abstract

Radiation processing of polymers is a well-established and economical commercial method of precisely modifying the properties of polymers. The industrial applications of the radiation processing of plastics and composites include polymerization, cross-linking, degradation and grafting. Radiation processing mainly involves the use of electron beams from electron accelerators. The Thermoplastic Elastomer (TPE) was used in this research and the mechanical properties were investigated at the ambient temperature. Results demonstrate that TPE has higher values of tensile strength with the increased irradiation dose and it has decreased elongation at break. This behaviour leads to the expansion of these materials in the automotive and electrical industry.
