Impregnation

Impregnation allows us to introduce new functions to the foam. By adapting the impregnation formulation, we can for example, improve fire retardancy. 

The impregnation technology shown here involves dipping the foam into a bath, squeezing it and then drying it in an oven. The overall dimension of the cell remains the same but the window opening becomes smaller, the struts become thicker and the overall density of the foam increases due to the extra coating material on the foam struts.
