Foam Brick
A foam brick is a cooling element with a foam core that holds the cooling medium, enclosed in a film casing. The core gives the element its geometry and retains it when frozen. This allows its position in the insulated shipper to be defined reproducibly.
What is the practical difference?
- The shape is largely retained during freezing and thawing. This makes defined arrangements and checks during packing easier.
- The foam core can retain liquid and reduce leakage if the film is damaged. An intact casing is still required.
- The filling determines the thermal application: THERMOCON offers water-based foam bricks and PCM versions at +5 °C and −21 °C.
Can a foam brick replace a gel pack?
Not without assessing the configuration. Dimensions, filling quantity and heat transfer may differ. A substitution must be compatible with the tested packout and preconditioning. Foam bricks are therefore a distinct format, not a promise of a particular shipping duration or temperature.
