  • 13X molecular sieve powder




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

The powder is also available as pastes (50% dispersion in castor oil). Chemxin zeolite powders and pastes are added to solvent-free one-pack and two-pack polyurethane systems, primarily to remove water. Applications include coatings, adhesives, sealants, casting resins, sports floors and elastomers.

Chemxin 13X molecular sieve activation powder:

As a functional filling material, it is widely used in medicine, food, rubber, plastics, painting, coating and cosmetics industry.
