Our Products
Molecular sieve powder is a finely ground, activated form of zeolite used for moisture removal and adsorption in coatings, adhesives, sealants, and polymer systems to prevent moisture-related defects, especially in PU system.
Molecular sieve is a porous crystalline material used to selectively adsorb moisture and gases, widely applied in drying, purification, and separation processes across chemical, petrochemical, and pharmaceutical industries.
Activated alumina is a highly porous, adsorbent material commonly used for drying gases and liquids, as well as removing impurities like fluoride, arsenic, and sulfur compounds in water treatment and industrial processes.
