| Brands | Honeywell Performance Materials and Technology (China) Co., Ltd. |
| Chemical formula | Na12[(AlO2)12(SiO2)12]·xH2O |
| Brief introduction | Type 4A molecular sieve series A type crystal structure sodium type, is an alkali metal aluminosilicate, 4A type molecular sieve can adsorb molecules with a critical diameter not greater than 4 Å. |
| Applications | Type 4A molecular sieve adsorbent is suitable for static dehydration in a closed gas or liquid system, as a static desiccant in household refrigeration systems, pharmaceutical packaging, electronic components, and perishable chemicals, and as a dehydrating agent in paint and plastic systems . Type 4A can also be used for drying saturated hydrocarbon materials in industry. Any molecule that can be adsorbed on the 3A molecular sieve can be adsorbed on the 4A molecular sieve. |
| Regeneration | Type 4A molecular sieve can be regenerated and reused by purging or vacuuming when the temperature is increased. The degree of regeneration (dehydration) depends on the humidity and temperature of the purging gas. |
| Delivery | 4A molecular sieve has two forms, 4×8 and 8×12 spherical. Load and ship in sealed galvanized drums or packaging bags. |
