FOAMAT® 285 Universal Foam Qualification System Figure 1: The Universal Foam Qualification System FOAMAT 285 is supplied with different test containers. The base system consists of the mechanical set, 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. Disposable cups can also...

rigid foam height master diel. polarization Figure 2: The curves show the reaction of a rigid foam measured by FOAMAT 285 with FPM/CMD 150. 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. It features an 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....

bottom 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 blow off point of flexible...

Figure 6: Size comparison of two FOAMAT 285 test containers: The FPM 70 (left) is designed for rise height and pressure measurement of high density foam samples. The picture shows a sealing foam in a 70mm cardboard cylinder. The Advanced Test Container ATC (right) is heatable from the bottom to the top and has reverseconical inner walls. The lower part contains an FPM/CMD 150 device for pressure and polarization measurement. The insulated upper part can be lifted to ease the ejection of the cured foam sample. weight due to the release of blowing agents and volatile components during foaming process,...

low density flexible foam rise height covered with a release agent, the foam sample can be removed easily from the device. Reliable Test Results Due to consistent temperatures, the measurement results of ATC are more comparable to the production situation. The decrease of the dielectric polarization reveals information about the curing process. As expected, curing goes faster at higher temperatures and more foam volume is generated. The pressure data is very consistent when measured with ATC. In combination with the Foam Qualification System FOAMAT 285, the ATC is a versatile accessory for Figure...

The start time and rise time are evaluated from the rise height data. The curing time is determined from the gradient of the dielectric polarization. Figure 12: The Analog Mixer can be connected directly to the MIXER socket of the controller unit. The mixer is then operated by the FOAMAT 285 foot switch. During the test procedure the mixer is automatically switched off after the mixing time....

SubCASE® Pot Life and Curing Monitor for Reactive - Coatings Adhesives Sealants Elastomers based on reactive - PU, EP, UP, and MMA formulations Figure 19: The Test device SubCASE HT measures the pot life and the curing of reactive plastics. It is designed for high reaction temperatures. The core temperature is measured by a reusable thermocouple inserted vertically into the center of the plastic sample. Pot Life Monitor SubCASE is a laboratory device for measuring the pot life and the curing behavior of Coatings, Adhesives, Sealants and Elastomers (C.A.S.E.). The measurement device is especially...

cylinder, which forms the test container is fastened with the clamp mechanism. The mixing time, the test time, and the heater temperature are free selectable parameters in the software SUBCASE. The reactive mixture can automatically trigger the data acquisition when poured into the test container. After the pouring, the cover plate together with the thermocouple (Fig. 22), that is protected by a disposable glass tube, can be placed onto the clamp mechanism for core temperature measurement. After completion of a test, physical values like pot life and curing are evaluated from the measured curves...
