To meet the stringent requirements of PVC compounds intended for use in injection molded cabinets, housings and other electrical applications, impact modifiers are required which permit good melt flow while processing and allow passage of falling ball impact at −20°C. Extensive testing is described as differentiating the low temperature toughness imported by two similar impact modifiers which give the same mold flow in modified PVC.
