Description

General description

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).
