Description General description Silicone oil AP 150 Wacker is a conventional electrorheologic (ER) fluid. It was employed as an insulating medium during the poling of hard ferroelectric ceramics. Silicon oil is composed of a mixture of hydrophobic polymeric and monomeric compounds, containing silicon-oxygen bonds. Its physical and chemical characteristics have been reported. The utility of silicon oil as a vitreous substitute has been studied. Application Silicone oil AP 150 Wacker was used to prevent the water evaporation during rheological characterization of injectable polysaccharide system based on calcium alginate hydrogel and two dextran methacrylate derivatives. It may be used for the determination of chloroplast volume by the silicone oil filtering centrifugation technique. Packaging 1 L in poly bottle 250 mL in poly bottle
