Modification and Properties of EVA Foamed Material with Hemp Stem Powder

Abstract

In this study, a certain amount of hemp stem powder was added into ethylene-vinyl acetate (EVA) copolymer foam system by molding, and the improvement of properties of composite foam system with different hemp stem powder content of 0-30% was studied. The results showed that hemp could decrease the hardness and density of the composite foam system, improve the resilience and compression deformation rate, and have excellent moisture absorption and quick drying properties and antibacterial properties. The results show that the foaming system with 10%-20% hemp stem powder has the best comprehensive mechanical properties, which can be used in shoes.
