The foam pressure measurement device is designed to measure the rise pressure of the foam. Pressure is build up within the foam post the component setting. The formation of stable cell walls prevents expanding of the foam to release blowing agents. The wall elements, panels or sheet metal are all stressed at right angles to the foam flow direction when they are foam backed to ensure insulation or rigidity. The production equipment needs reinforcement or support as high pressure forces are generated. As the pressure risers, the forces are measured as the internal local stress within the foam critically depends on the foam rise height. FPM (Foam Pressure Measurement) device measures this rise pressure. The FPM replaces usual test cups. The rise curve reflects the dynamics of blowing agent generation. The rise pressure reflects the cell properties that s affected by polymerization reaction.
