Molecular Sieve Powders 3A are incorporated into the Swiggle Strip in the spacer of insulated glass windows to adsorb water.  This in turn prevents the negative and positive pressures inside the double pane window.  The benefit of this is to reduce glass deflection, stress and breakage, reduced heat and sound insulation, and  loss of seal integrity.

Molecular Sieve 3A  Beads are spherical beads are incorporated into the spacer bar of an insulated glass window to adsorb water and prevent off gassing and window deflection.
