KolBoy GelPaks are filled with white granules made of a superabsorbent polymer refrigerant (SAP) crystals. Six mil polybags insure that the crystals will not leak onto valuable products. When water is added (SAP) will absorb 125 times its weight in water. After freezing, two pounds of Gel absorbs 36,000 calories of heat energy upon phase change from ice back to gel. KolBoy GelPaks may be refrozen and used again for certain applications. These may be supplied separatelsy with our thermal shippers to increase the interval that products remain cold.

Custom products can be designed without the added expense of mold casting for small production runs, specialty foams, and architectural detailing. Hot wire cutting using advanced CNC technology allows for intricate shaping of various foams to custom requirements of density and flexibility. From simple to complex, our design team can find the perfect solution to meet your needs.
