Abstract
In this work, zinc berate is used as synergistic agent in EVA-Mg(OH)(2) fla me-retardant (FR) formulations. High zinc berate content leads to a signifi cant improvement of flame retardancy during cone calorimeter experiments. B lowing measurements reveal significant modification of the structure due to the presence of zinc berate. To estimate the resistance of this structure under strength, blowing measurements were carried out under two different p ressures. Viscosity measurements helped to elucidate the foaming process. F inally, zinc berate can be understood to be a binder (flux agent). (C) 2000 Society of Chemical Industry.
