Synthetic 300mesh Type 3a Molecular Sieve
Synthetic 300mesh Type 3a Molecular Sieve
Product Description
300 mesh 3A activated molecular sieve powder for IG rubber Product Description. Activated Molecular Sieve Powder is dehydrated synthetic powder molecular sieve. With the character of high dispersibility and rapid adsorbability. It is used in some special absorptive circumstances,
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.
