The conductivity aspect is a vital index to measure the warmth-insulation and cold-insulation result of the heat-preservation substance. The lessen the conductivity component is, the greater the heat-insulation functionality is going to be. The conductivity component of the materials is 0.034w/m�?k at an average temperature 0 �?.
