Molecular sieve activated powder or activated zeolite powder, is obtained by calcining molecular sieve raw powder at high temperature. Beause the raw powder loses most of the moisture during the calcination process, the activated zeolite powder has strong activity and can be directly used in production as an adsorbent with selective adsorption.
3A molecular sieve activated powder or activated zeolite powder, used as amorphous desiccant added to insulating glass composite strips; to avoid foam generation in polyurethane products to extend service life.
4A molecular sieve activated powder or activated zeolite powder, used as additives for coatings, paints, resins and certain adhesives to reduce moisture, to eliminate air bubbles, and improve material uniformity and strength.
5A molecular sieve activated powder or activated zeolite powder, used as adsorbent of impurities such as moisture that affect polyurethane product quality without changing physical and chemical properties; and selective adsorbent added to specific polymers or coatings.
13X molecular sieve activated powder or activated zeolite powder, used as functional filling material of medicine, food, rubber, plastic, paint, coating and cosmetic industries.
