Development of a silica-free silicone system for medical applications.
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.
