USLPore® FA SL 400 is specifically developped for higher pump pressure and occuring shearing forces while pumping. Shear forces attack the foam bubbles menbrane and are leading therefore to instabiliy and volume loss. With USLPore® FA SL 400 the resitance to pumping will be increased drastically and therefore the overall stability of the final foamed concrete or cellular lightweight concrete.
Compared to the USLPore® FA SL 200, the FA SL 400 type is even more resistant to shear and pressure.
