Extremely High Water Adsorption Capacity
4A molecular sieves exhibit a strong affinity for water molecules, enabling deep drying at the ppm level.
High Mechanical Strength
The formulation of high-strength synthetic zeolite and a uniform binder gives 4A molecular sieves high compressive strength and low abrasion rate.
Multiple Regeneration Capabilities
4A molecular sieves can be repeatedly regenerated through heating or reduced pressure, restoring adsorption performance to over 95%.
Packaging and Transportation
4A molecular sieves are packaged in various forms, including 25kg composite valve bags, 150kg iron drums, and 1 ton bulk bags. Custom packaging is available upon request.
During transportation, moisture-proof containers or coverings are used to prevent moisture absorption and performance degradation. Sea and land transportation, as well as long-term warehousing, are supported.
