Neralit polyvinyl chloride is produced by suspension polymerisation of vinyl chloride in an aqueous medium in the presence of catalysts and suspension stabilizers. The resulting product is a fine, white, easily-pourable powder made up of grains with narrow particle size distribution. The properties of suspension Neralit PVC powder depend on the additives used during polymerisation, on the temperature regime of polymerisation, on the method and intensity of mixing the suspension, and on a number of other factors at work during production.
