Abstract:
The present invention relates to a reactive cell opener composition that includes a base oil, and a metal salt of a fatty acid having a hydroxyl group coupled to an isocyanate group. The invention also relates to a polyol composition that includes a polyol, a foam stabilizer, and a cell opener mixed with each other. The present invention also relates to an open-celled polyurethane foam manufactured from a polyol composition.
Abstract:
A vacuum insulation glass panel includes a pair of insulation glass stacked with a predetermined interval therebetween, a plurality of spacers to support the pair of insulation glass at multiple points within a support area defined in a vacuum layer between the pair of insulation glass, and a non-conductive sealing portion disposed along edges of the pair of insulation glass to make the support area air-tight from the exterior. Also, a refrigerator with the vacuum insulation glass panel is disclosed. Therefore, the non-conductive sealing portion is located at the edge portions of the pair of insulation glass, which are stacked by each other to define the vacuum layer, which allows preventing of a shape deformation due to changes in external temperature and reducing of heat transfer coefficient down to a predetermined level.
Abstract:
A vacuum insulation panel includes a core material having a bending groove at at least one surface thereof, and an envelope material to cover an outer surface of the core material and an inner surface of the bending groove. Also, a refrigerator with the vacuum insulation panel and a manufacturing method for the vacuum insulation panel are provided.
