Ethylene Vinyl Acetate Copolymer

Highly filled bio-composites based on ethylene-vinyl acetate copolymer (EVA) with cellulose and wood flour were prepared in the previous parts of the study. The aim of this work was to dilute them with a polyethylene (PE), to prepare new bio-composites with lower EVA content and to investigate the effect of EVA/PE ratio on the mechanical properties. It was shown that melt flow index (MFI) and elongation at break increased additively with an increase of EVA content in the composition, but yield strength had an inverse tendency. The obtained results are extremely useful for choosing the right composition for the industrial implementation.

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.

Ground tire rubber (GTR) was reclaimed and modified with 10 phr of ethylene-vinyl acetate copolymer via low-temperature extrusion process. Processing, physico-mechanical properties, volatile organic compounds emission, and recycling possibility were investigated. In order to better understand the impact of used modifiers, their efficiency was compared with trans-polyoctenamer, which is an additive that is commercially dedicated to waste rubber recycling. The results showed that a relatively small amount of ethylene-vinyl acetate copolymer improves the mechanical properties of modified reclaimed GTR and also allows further recycling by multiple processing without the deterioration of performance after three cycles.
