Polymer foams are porous materials that have a large number of tiny air pores in their structure. Among the different types of these foams, ethylene vinyl acetate (EVA) foam is used as one of the most widely used in various industries such as packaging, shoes, automotive and bumpers. Physical and mechanical properties of EVA foams are affected by changes in cell structure, concentration and type of crosslinking and blowing agents, process parameters and other factors. To achieve the desired properties in these foams, it is possible to combine them with other rubbers. The combination of two or more polymers in order to produce a product with the required properties for specific uses has become very important in the industry. Due to its high tensile strength, good flexibility at low temperatures, excellent resilience, resistance to permanent deformation and good tear strength, natural rubber (NR) can be successfully combined with EVA and foams with uniform cell size and favorable physical and mechanical performance. create Nowadays, preparing EVA/NR foams and combining them with other polymer materials has become one of the important topics in polymer research to improve their performance in different conditions. This research provides a comprehensive overview of the effective factors and their effects on the properties of EVA/NR foams, including physical, mechanical and structural properties.
