The thermal conductivity of the foam fresh-keeping box refers to the heat transferred through an area of 1 square meter within 1 hour with a material with a thickness of 1 m and a temperature difference of 1 degree (K, °C) on both sides of the material under stable heat transfer conditions. Thermal conductivity reflects the thermal conductivity of the material, and is also the main thermophysical property of the foam fresh-keeping box. The thermal conductivity of the general foam fresh-keeping box increases with the increase of temperature, moisture content and bulk density, and the thermal insulation effect decreases. The unit of thermal conductivity: watt/m•degree (W/m•K, where K can be replaced by °C) The thermal conductivity is related to the composition, density, moisture content, temperature and other factors of the material.
Amorphous structure, lower density material, lower thermal conductivity. When the moisture content and temperature of the material are low, the thermal conductivity is small. Materials with low thermal conductivity are usually called foam fresh-keeping boxes, and materials with thermal conductivity below 0.05W/m•K are called high-efficiency foam fresh-keeping boxes.
