Cell openers are substances added to polyurethane foams to ensure that the foam structure has a predominantly open cells, enabling it to ‘breathe’.

Foam, in which cell openers have been used, has a larger value of air permeability. Water vapour is not condensed on the foam surface, which prevents mould growth. In addition, such foam does not shrink after cooling.

Cell openers, which are also known as pore regulators, weaken the walls of cell. Cell openers generate increased pressure in the cells during the formation of bubbles (foaming), which damages cell walls in weaker points. In order to reduce the strength of cell walls, surface-active substances are used (surfactants).
