Recycling industry

Application Areas: Recycling of PET-bottles, foils/films, PS-cups as well as mixed plastic materials, recycling of sized packaging board. The selected STRUKTOL products offer a well-balanced relation between foam destruction, foam prevention and deaeration. The prevention of foam in advance is advantageous for a smooth factory process; the antifoam product should be added continuously in concentrated form by a dosage pump. A sufficient distribution in the medium should be achieved.

The formation of foam depends on foam active substances in the process water (e.g. proteins, tensides, modified cellulose), temperature, intensity of water circulation and water treatment. The most favourable dosage quantity and the best adding point depend on factory conditions and have to be found out by trials.
