Molecular sieve activation powder is produced by subjecting the original molecular sieve powder to a staged heating process and high-temperature activation treatment, removing moisture from the molecular channels. This results in a powder with an open skeletal structure and active adsorption space, serving as an efficient adsorbent.
Removing trace moisture is a critical issue in the production of polyurethane products. Trace moisture in polyols can react with isocyanates, generating carbon dioxide and causing foaming; it also shortens the product’s usable period (open time).
JOOZEO‘s molecular sieve activation powder, with its excellent dispersion properties and rapid adsorption characteristics, effectively addresses this problem. It can dehydrate moisture-sensitive formulations, precisely removing reaction water and other impurities from the materials. Adding activation powder to the polyurethane system allows selective adsorption of trace moisture in the formulation, effectively inhibiting side reactions, thereby reducing bubble formation and extending the usable period.
Additionally, JOOZEO’s molecular sieve activation powder possesses outstanding chemical stability, ensuring that it does not undergo any chemical reactions with the system during use, thereby maintaining the product’s stability and reliability.
