MILLIFOAM® PB foaming agents from Innospec use sophisticated surface chemistry to help produce gypsum plasterboard with a tailored, uniform density.

The foam structure generated during plasterboard production has a direct influence on board density and performance.

The MILLIFOAM® PB series from Innospec are formulated anionic surfactants with varying coalescence levels for different resulting void sizes:

The below list of MILLIFOAM® products are specifically engineered for plasterboard applications, providing maximum foaming power in soft and hard water, saturated brine, and gypsum solutions:

Low coalescence / High density

MILLIFOAM® PB 523
