Messtechnik GmbH FOAMAT® 285 Universal Foam Qualification System FOAMAT® Figure 1: The Universal Foam Qualification System FOAMAT 285 is supplied with different test containers. The base system consists of the stand, the ultrasonic fan sensor LR 4, the controller unit, and the PC software FOAM. The Advanced Test Containers ATC and ATC XL (left) are the most sophisticated test containers. The innovative Box Foam Container BFC 200 is used for slabstock foam. The Foam Pressure Measurement devices FPM 2, FPM 70 and FPM 150 (right) use disposable cardboard cylinders of different diameters....

Rise height (H), reaction temperature (T), rise pressure (P), and dielectric polarization (D) are recorded simultaneously by the software FOAM. The colored areas are master curves for QC. integrated fan for air homogenization, an ultrasonic transducer, and a temperature gauge for speed of sound compensation. All types of foam can be measured, including flexible molded and slabstock foams, semi-rigid foams, and rigid foams with strong heat release. The...

Messtechnik GmbH FOAMAT® of the cylinder, where the applied force is measured by a load cell. The expansion volume is confined by the walls of the cardboard cylinder and the FPM base plate. A thin foil protects the base plate against contamination. The FPM replaces normal test cups and boxes. Whereas the rise curve reflects the blowing agent generation, the rise pressure mirrors the cell properties, which are affected by the polymerization reaction. Pressure measurement can yield valuable information about the effects of catalysts on gelling. Furthermore the rise pressure determines the...

Messtechnik GmbH provided in combination with the pressure measurement device FPM. Balance Integration In order to obtain reproducible measurement data, the reaction components must be weighed exactly. Despite the utmost care on behalf of the user, remnants adhering to the stirrer and remaining in the mixing cup may lead to uncertainties in the tested foam mass. The integration of a laboratory balance into the FOAMAT system (Fig. 5) automatically records the mass of each component in the batch documentation. Additionally, the loss of weight due to the release of blowing agents and volatile...

Messtechnik GmbH Figure 8: The Advanced Test Container ATC XL (center) has four times the test volume of the standard ATC (right). Each of them comprises an upper and a lower part, which are clamped by spring locks. The foam sample (left) can easily be ejected through the bottom opening of the upper part. between laboratory investigation and the production situation. This is critical especially for PIR and phenolic foams which only cure at elevated temperatures. The Advanced Test Container ATC and the larger version ATC XL (Fig. 8) overcome this problem by two temperature controlled closed...
