3A Zeolite Molecular Sieve Powder

3A Zeolite Molecular Sieve Powder For Polyurethane Systems

Activated Molecular Sieve Powder PM Molecular Sieve Powder has the character of high dispersibility and rapid adsorbability. It is used in some special absorptive circumstances, such as being formless desiccant, being adsorbent mixed with other materials etc. Activated Molecular Sieve Powder 3A has thr pore size of 3A, it can remove water eliminate bubbles, increase uniformity and strength when being additive or base in paint, resin and some adhesives. 3A Activated Molecular Sieve Powder can also be used as desiccant in insulating glass rubber spacer.
