Dispergator for sandwich panel production lines Mixing concept Because of changes in regulations on additives and the complexity of for-mulations, items in the Polyol blend viscosities were varied and are very difficult miscible or even immiscible. The result is a foam very difficult to implement, surfaces in contact with the plate full of bubbles, adhesion problems, shrinkage problems, bubbles, … To circumvent the lack of miscibility of the components we have developed two elements allowing a dispersion of additives and the gas into very small particles homogenously distributed in the Polyol. Therefore, when the Polyol is mixed in the mixing-head with Isocyanate, additives are much more reactive and there is no concentration of gas or random foaming agents that create bubbles surface states or « potato fields. ». The disperser is to this day an essential element of the production units of polyurethane foams and have a great effect on PIR. It is available as low pressure (air...
