5A activated molecular sieve powder 2-4um for CO2 and H2S adsorption in special plastic and polyurethane mixtures

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.


zeolite powder


5A molecular sieve activation powder:
In the production of polyurethane products, the product itself can not change the physical and chemical properties under the condition of adsorption, affecting the quality of products impurities such as water; can also be used as a selective adsorbent added to specific polymers or coatings, CO2 and H2S adsorption gas generated in the production process.
