Novel antibacterial mouthguard material manufactured using silver-nanoparticle–embedded ethylene-vinyl acetate copolymer masterbatch

Use of Polyolefin as Mouthguard Material as Compared to Ethylene Vinyl Acetate

Effect of ethylene vinyl acetate (EVA) closed cell foam on transmitted forces in mouthguard material.

OBJECTIVES To compare transmitted forces through ethylene vinyl acetate (EVA) mouthguard material and the same EVA material with gas inclusions in the form of a closed cell foam. METHOD EVA mouthguard materials with and without foam gas inclusions and 4 mm thick were impacted with a constant force from an impact pendulum. Various porosity levels in the foam materials were produced by 1%, 5%, ...

Beneficial effects of air inclusions on the performance of ethylene vinyl acetate (EVA) mouthguard material.

OBJECTIVE To investigate the impact characteristics of an ethylene vinyl acetate (EVA) mouthguard material with regulated air inclusions, which included various air cell volumes and wall thickness between air cells. In particular, the aim was to identify the magnitude and direction of forces within the impacts. METHOD EVA mouthguard material, 4 mm thick and with and without air inclusions, wa...

Enhanced Controlled Transdermal Delivery of Mexazolam Using Ethylene-vinyl Acetate

   Repeated oral administration of mexazolam, an anti-anxiety agent, may cause adverse effects such as gastric disturbance, drowsiness, and ataxia due to transiently high blood levels. Transdermal administration would avoid the systemic side effects and gastric disorders after oral administration. We have developed a matrix using ethylene-vinyl acetate (EVA), a heat-processible and flexible mat...

study 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...
