The conductivity aspect is an important index to evaluate the warmth-insulation and cold-insulation impact of the heat-preservation content. The lessen the conductivity factor is, the better the heat-insulation functionality are going to be. The conductivity factor of this materials is 0.034w/m�?k at a median temperature 0 �?.
