Ethylene-Vinyl Acetate Foam

Polymer foam is a kind of porous polymer material with a significant number of small foam pores inside its matrix. Ethylene-vinyl acetate (EVA) polymeric foam products have emerged as the most popular type of foam to be used in a variety of industries, including packaging, pharmaceuticals, mouth guards, sports, running shoes, health sector, automotive, cushioning materials, and many others because of its versatility. EVA foam is the locked/closed cell copolymer of ethylene and vinyl acetate. The physical properties of EVA foams might vary because of changes in cell structure, concentration/type of crosslinking agent and blowing agents, process parameters, and other factors. Currently, the preparation of EVA foams blended with other polymericmaterials has become a hotspot in polymer research to improve their functionality aswell as tomake themmore effective substitutes for rubber. This chapter presents a broad overview of the different factors involved and their effects on the typical properties of EVA foams—like physical, mechanical, and morphological properties—and also discusses several approaches explored for enhancing the inherent properties of EVA foams with their applications.
