Knowing something about how foam is made is the only way to understand why foam properties vary so much. Flexible polyurethane foam is produced by the reaction of two key chemicals. These are polyol and isocyanate. These are thoroughly mixed with other chemicals in a high-power mixer, and the foam reaction begins immediately. Bubbles form and the mixture expands. This can be compared to the rising of bread or cake while baking. After a certain period, the reaction is completed.

Slabstock foam process: Two basic processes are used in foam production. In one, the chemical mixture is poured onto a moving conveyor where the reaction and expansion take place. On the conveyor, the foam rises like a cake, and rectangular blocks are obtained at the desired length. These blocks are kept in stock for 48 hours for curing. This production process is called the slabstock production process. After curing is completed, the foam is processed as desired. Many foams for the furniture and mattress industry are produced this way.

In addition to the polyol, isocyanate, and water used to produce foam, the final properties of the foam can be changed with various chemical additives. Birlik Sünger performs slabstock production with its Laader Berg machine - Maxfoam technology. It can produce foam in the range of 150 cm - 240 cm with the Laader Berg machine. Birlik Sünger has met market demands until today by preparing formulas in desired densities and properties with its superior chemistry knowledge and half a century of experience. It will continue to be among the leaders of its sector with its developing technology and potential to create new products from now on.

The World of Foam Flexible polyurethane foam is one of the most variable and versatile materials ever discovered. Although flexible polyurethane foam is seen as a simple product, it has a complex structure. It can be produced in an infinite variety of properties. Even if two foams look completely similar, they can feel completely different when touched and perform differently. However, foam properties can be defined and determined very precisely. The foam industry has defined several measurement and test methods to do this. And with the use of these measurements, it is possible to determine the right foam for the right application.

Although several different measurements and tests are used to select the foam to be used in a specific product, in almost every selection, three elements determine the final goal:

Support: The ability of the foam to support the weight of an object or person in appropriate amounts,

Comfort: The foam support ensuring the user feels good and providing not just support but also comfortable use,

Durability: The ability of the foam to remain without losing its original properties during the period of use. These are the basic benefits that allow the foam to provide support, and if the needs in each of these three areas are evaluated first, choosing the suitable foam for the desired use becomes quite simple. While good support, comfort, and solid foam should be used in the seating areas of sofas, comfort is necessary for the arm and back buffers of the same sofa where support requirement exists but supporting weight is not necessary.
