Improved Adhesion of UV Treated EVA Copolymer by Adding Small Amounts of Fillers

The influence of adding small amounts of calcium carbonate or sepiolite fillers on the adhesion properties of UV surface‐treated ethylene vinyl acetate copolymer (EVA) was studied. In this paper, it has been demonstrated that the addition of 3‐7 wt% filler enhanced the extent of the surface modifica...

Zusammenfassung:The influence of adding small amounts of calcium carbonate or sepiolite fillers on the adhesion properties of UV surface‐treated ethylene vinyl acetate copolymer (EVA) was studied. In this paper, it has been demonstrated that the addition of 3‐7 wt% filler enhanced the extent of the surface modifications (wettability, surface chemistry, roughness) and increased the adhesion of EVA. These effects were more marked when 7 wt% sepiolite filler was added to EVA, likely due to its higher aspect ratio.
