Research overview:
In this study, the heat conductivity and thermal contraction coefficient of the virgin material of hard urethane foam using HCFC-141b as constitute fleon is measured over a temperature range to the temperature of liquid nitrogen, and thermal shock test and accelerated aging test are carried out to elucidate the durability of that material.
