SEIDO Vacuum Insulation Panel Mahyado Board Cooler Box Soft Cooler Small Cold Preservation Freeze Long Time Cold Preservation Ice Pack Set of 4

Vacuum insulation panels are used in expensive cooler boxes, and are thin yet highly insulating materials. Traditionally, it is used inside cooler boxes, but we have improved it so that it can be used as an inner lid. SEIDO's vacuum insulation panels use high-density composite fibers for the side materials. Made of durable fabric that is woven with composite fibers that are resistant to scratches and tears. The core material uses an inorganic insulation material. By compressing and sealing the core material in a vacuum, we have achieved high insulation performance despite being ultra-thin, something that could not be achieved with conventional insulation materials. The thermal conductivity of vacuum insulation panels is 0.008w/mk, which means they are four times more efficient than the urethane foam insulation used in expensive cooler boxes. The purpose is to maintain cold storage capacity without compressing the contents of the cooler box as much as possible. When 1.1kg of rock ice was left at a temperature of 30℃ for 6 hours, the remaining amount of ice increased from 35% to 55%!
