Description générale

Poly(ethylene-co-vinyl acetate) (PEVA) is a flame-retardant material with good mechanical and physical properties. It is majorly used as an insulating material in wire and cable industry.

Application

Correlation between Cohesive Energy Density, Fractional Free Volume, and Gas Transport Properties: This study explores the properties of EVA materials that affect their gas permeability, important for applications like packaging and barrier materials (Kubica & Wolinska-Grabczyk, 2015).
The Thermal and Mechanical Properties of EVA and its Crosslinked Analogues: This research investigates how crosslinking affects the thermal and mechanical properties of EVA, which could interest material scientists working with polymers (Wang & Deng, 2019).
Investigation of morphological, rheological, and mechanical properties of cyclic olefin copolymer/EVA blend films: This study focuses on the blend properties of EVA with other polymers, providing insights useful in academia and material science (Durmus et al., 2018).
Fabrication, characterization, and properties of EVA/magnetite nanocomposites: Relevant to material scientists, this research discusses the incorporation of magnetite nanoparticles into EVA for enhanced properties (Ramesan, 2014).
