Zeolite 4A Powder Desiccant
 Zeolite Molecular Sieve 4A Powder For Polyurethane Activated Molecular Sieve Powder 4A, is dehydrated synthetic powder molecular sieve. It has very strong activity because it loses most of its moisture during the high temperature roasting process. “Packing-mall" Activated 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. Zeolite 4A Powder Desiccant can remove water eliminate bubbles, increase uniformity and strength when being additive or base in paint, resin and some adhesives. It can also be used as desiccant in insulating glass rubber spacer. |
