The line change of this material is
Linear change ≤2.4% at 1150 ℃ × 6h
(200 ~ 400) C × 6h
Line change ≤0.2%
Linear change refers to the crystallization, shrinkage of the insulation material at high temperature, which destroys the porous structure of the material and deteriorates the performance. The linear change of the general insulation material is 5 to 10 times that of the material.
Ordinary materials cannot be folded in half 180 degrees and the material has good folding resistance. No breakage or breakage will occur when folded in half several times, thus bringing convenience to the construction.
The material has good thermal conductivity (Kcal / m · h · ℃) 0.03 at 200 ℃, 0.06 at 400 ℃, 0.09 at 600 ℃ and 0.1 at 800 ℃.
