Polar brick this international quality foam brick (also known as ice bricks, gel bricks, and foam bricks) are made of phenolic foam is superior in cold retention, outlast all other refrigerants due to an even rate of heat absorption. Ideal for tightly fitting packaging configurations, when used with properly insulated containers will maintain cold room condition upto 48 hours. Globally popular because of its ability to retain its shape, light weight and excellent cold retention properties. The thermal mass of the gel coupled with interior insulation ensures the stability of the refrigerated temperature system
