Mechanical behavior of ethylene vinyl acetate copolymer (EVA) used for fabrication of mouthguards and interocclusal splints.
In the present investigation, an experimental dental arch model fabricated in epoxy was assayed in Kratos universal testing machine to study the mechanical behavior of ethylene and vinyl acetate copolymer (EVA) in the form of mouthguard for sports and flat plate. The following variables were considered: thickness (3 and 4-mm plates), temperature (room and mouth temperature) and presence/absence...

متن کاملstudy of ethylene/vinyl acetate transformation to ethylene/vinyl alcohol copolymer by nmr and dsc
hydrolysis of ethylene-vinyl acetate copolymer in alkaline conditions using two systems of naoh/methanol and koh/isopropanol has been studied and the formation of ethylene-vinyl alcohol copolymer was systematically examined using nmr spectroscopy and dsc measurements. vinyl acetate weight percentage and the degree of hydrolysis were calculated from nmr spectroscopy and it is shown that hydrolys...
متن کاملThe rheological behavior of collagen dispersion/poly(vinyl alcohol) blends
Blends of collagen dispersion (COL) with poly(vinyl alcohol) (PVA) in different weight ratios were investigated by oscillatory rheometry, Fourier transform-infrared spectroscopy and scanning electron microscopy. It was found that even with 80% of PVA, the COL/PVA blends behaved more like collagen dispersion than pure PVA solution in the dynamic thermal and frequency processing, for instance, a ...
متن کاملEffect of Morphology on Rheological Properties of Ethylene-vinyl Acetate Copolymer (eva) (containing 40 Wt% Va Content) Nanocomposites
The combination of Ethylene-vinyl acetate copolymer (EVA) with nanoclay has wide commercial applications (such as packaging films and cables), which depend on the vinyl acetate contained in the main chain. As the vinyl acetate content increases, the copolymer presents less crystallinity and different mechanical behavior. EVA with 40 wt% vinyl acetate content (EVA40)/ organoclay nanocomposites w...
