Effect of sepiolite content on mechanical, thermal and flammability properties of ethylene vinyl acetate nanocomposite

Polymer/clay nanocomposites are a new class of composite materials consisting of a polymer matrix with dispersed clay nanoparticles. Ethylene vinyl acetate (EVA)/Sepiolite and EVA/modified Sepiolite (M-Sepiolite) nanocomposites were prepared by melt extrusion using a counter-rotating twin-screw extr...
