CORE MATERIAL FOR VACUUM HEAT INSULATION PANEL, VACUUM HEAT INSULATION PANEL AND REFRIGERATOR

摘要

PROBLEM TO BE SOLVED: To provide a thermal conductivity rate equivalent to a thermal conductivity rate of a core material comprising glass fiber even when the core material is constituted of a resin fiber.SOLUTION: The core material for a vacuum heat insulation panel is a core material for a vacuum heat insulation panel which comprises the resin fiber and has the thermal conductivity rate equivalent to a thermal conductivity rate of a core material comprising glass fiber.SELECTED DRAWING: Figure 7
