Product Details

Activated Molecular Sieve Powder is dehydrated synthetic powder molecular sieve. With the character of high dispensability and rapid adsorb ability, it is used in some special adsorb ability, it is used in some special adsorptive circumstances, such as being formless desiccant, being adsorbent mixed with other materials etc.
It 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.
