Professional expanding foam

Professional

— polyurethane foam designed for professional use in jobs requiring high precision. To use this composition, a special gun is required, which must be purchased separately. In terms of performance, professional foam differs from household foam in the almost complete absence of deformation — it does not expand when cured and almost does not shrink when completely dry. Also, among the features of such compositions, one can note a rather large volume of cylinders (usually from 750 mL and above), an almost complete foam output and the ability to use one cylinder in several passes — the main thing is to keep the cylinder in a gun with a closed nozzle between runs.

Note that such compositions are expensive; therefore, it makes sense to purchase them only for those cases where accuracy and high quality are critical. For simple tasks, it is better to use household brands of foam.
