The conductivity factor is a very important index to measure the warmth-insulation and chilly-insulation outcome of the heat-preservation materials. The decrease the conductivity component is, the greater the heat-insulation efficiency is going to be. The conductivity variable of the material is 0.034w/m�?k at an average temperature 0 �?.
