I. Product Introduction
Our company produces 3A molecular sieve, a alkali metal aluminosilicate. The pore size of 3A molecular sieve is 3Å, mainly used for water adsorption, and does not adsorb any molecules with a diameter greater than 3Å. It is characterized by fast adsorption speed , regeneration times, crush resistance and anti-pollution ability, improving the utilization efficiency and extending the service life of the molecular sieve. It is an essential desiccant for deep drying, refining, and polymerization in the petroleum and chemical industry sectors.
II. Main Applications
3A molecular sieve is widely used in: drying various liquids (such as ethanol); air drying; refrigerant drying; natural gas and methane drying; unsaturated hydrocarbons and cracked gas 、 ethylene 、 acetylene 、 propylene , butadiene drying, etc.
Storage Conditions
Indoor storage at room temperature with relative humidity not exceeding 90%, dry, cool, and away from light.
Implementation Standard
In accordance with the national standard GB/T 10504-2017 superior product indicators.

Note: d value is the product particle size.
For products with d(1.5mm～1.7mm), the particle size is the percentage of samples with a bar length of 1mm～10mm in the total quantity; for products with d(3.0mm～3.3mm), the particle size is the percentage of samples with a bar length of 3mm～12mm in the total quantity.
The packaging water content is based on the factory inspection data.
