Study of Some Properties of Flame Retardant Composites

Polyvinyl chloride (PVC) has very widely use in industrial and electrical applications, and to improve the resistance viability of ignition for more safety in this application. The PVC is mixed with metals hydroxide such as aluminum hydroxide and magnesium hydroxide. Metals hydroxide modified by polyvinyl alcohol (PVA) solution to improve the compatibility with PVC.To study the effect of particle size on the fire resistance and mechanical properties, nano-powders were prepared by chemical process from metal oxides was used in this research.
