Development of a silica‐free silicone system for medical applications

Abstract
Filler‐free silicones are believed to be more blood‐compatible than those containing fillers. An ultrapure silica‐free room temperature vulcanizing silicone system was prepared and characterized using a swelling experiment, an infrared spectrometer, an x‐ray spectrometer, a scanning electron microscope and neutron activation analysis. The polymer was found to be suitable for medical applications needing an extremely smooth surface.
