SEM cross section morphology
It shows Y-Warm material contains nanometer-scale cell walls and independent micrometer-scale foam cells, very like a honeycomb structure. According to thermal insulation principle of porous materials, the thinner cell wall, the greater thermal resistance, and the better thermal insulation.
Cell thickness: 20-280 nm
Cell diameter: 30-190 μm
