Mechanical Properties of Superconcentrates Based on Ethylene-Vinyl Acetate Copolymer and Microcrystalline Cellulose

Abstract:

In the study, highly filled superconcentrates based on various grades of ethylene-vinylacetate copolymer (EVA) and microcrystalline cellulose (MCC) were studied. It is assumed that adding superconcentrates to various polyolefins will make them biodegradable in the environment. The influence of EVA rheological characteristics and the content of vinyl acetate (VA) groups on the properties of the superconcentrates were studied. It was shown that increasing the concentration of VA groups in EVA leads to an increase in the elongation at break of the composites; increase in EVA melt flow index (MFI) greatly reduces the basic mechanical properties of the composite.
