摘要: The thermal conductivity and the cellular structure as well matrix polymer morphology of a collection chemically crosslinked low-density closed cell polyolefin foams, manufactured by high-pressure nitrogen gas solution process, have been studied. With aid useful theoretical model, relative contribution each heat-transfer mechanism (conduction through solid phases radiation) has evaluated. radiation can be calculated using which takes into account dependence this with size, foam thickness, chemical composition, morphology. A simple equation, used to predict given material, is presented.
