The Maxfoam™ Process, invented by Laader Berg®, is based upon a number of components that combine to create optimal foam quality.
The Maxfoam™ Process can be seen as:
- On a Maxfoam™ machine the freshly mixed liquid chemicals are piped from the mixer into the bottom fed Multi-trough.
- Here the initial reaction takes place before the expanding foam flows on to the bottom paper, which is sliding on an inclined fall-plate.
- The foaming Multi-trough evenly distributes the foam-cream between the sidewalls. The Multi-trough outlet is set at 70 % of the final block-height, and the volume of the trough is adapted to the formulation and output.
- The fall-plate is adapted to the necessary length and configuration in such a way as to allow the foam to reach the horizontal conveyor as a fully expanded block. Number of fall-plate sections, length and angles are designed and adjustable to the formulation and output.
- Foam expansion takes place over the inclined fall-plates, using the gravity forces which expand downwards, eliminating friction between foam and sidepaper.
- The full expansion of the foam is reached at the end of the fall-plate.
Maxfoam™ is the world’s most used and preferred foaming process. Due to the optimization of the Maxfoam™ Basic Process, only Laader Berg® can provide the unique and tailored solutions that allow you to produce flexible polyurethane foams at optimal foam economy and qualities.
