Molecular Sieve 4A

Molecular Sieve 4A is used as a desiccant in an array of industrial applications. 4A molecular sieve means the molecules with the pore size of 4A0 or 4 angstroms are used for the adsorbing process. It simply signifies that molecules with the pores size larger than 4a cannot be used for adsorption. Generally, they are the sodium forms of the Type A structure.

Type 4a has reliable adsorption speed, higher resistance quality, and stronger adsorption, which are enough to enhance product life. Such type of molecular sieve is perfect to remove the moisture from liquids and gases. It is a universal dehydrating agent used in polar and non-polar media. This type of molecular sieve is the perfect desiccant for low inlet, humidity, with the temperature below 30-35% RH.

4A molecular sieves can be available in the form of beads, pellets and powder form.

Molecular sieve 4A is considered as one of the best desiccants for a variety of applications that includes:

  • For instrumental air drying (for ensuring a dew point of -60/-800C.
  • Dehydration of drugs, electric components, and unpreserved chemicals when packed
  • Removal of moisture in plastics and paints
  • Drying of Refrigerants
  • Drying of Natural gas, petroleum gas, and cracked gas
  • Dehydration of ethanol
  • Generation and purification of argon
  • Isomerization feed drying
  • Drying of air-filled or gas-filled insulating glass units
  • Dehydration of unsaturated hydrocarbons
  • Drying and purifying of Ammonia gas

Molecular sieve Type 4A can be regenerated and reused as per the needs. For regeneration process, it requires the removal of adsorbed moisture, water and other provisions at a hot temperature of 250 to 450 degrees. This temperature depends on when reached in the purge. To avoid any kind of accidental moisture adsorption, such molecular sieves are required to keep in an airtight container before using it. The adsorbed species include argon, SO2, CO2, carbon monoxide, C2H4, C3H6, C2H4, CH3CN2, CS2, CH3Br.

Molecular sieve powder has the ability to remove water & moisture, to eliminate bubbles, to increase the consistency & strength when mixed in paint, resin and other adhesives. It works as a desiccant in an insulating glass rubber spacer. It is advisable not to unpack the products or goods to avoid exposure in the air before their use. Always remember to keep such products at a dry place.


Applications & Uses of molecular sieve powder

  • Storage protection for metallic pigment paint
  • Adsorbing carbon dioxide, hydrogen chloride, etc. from plastic formulations
  • Cosmetic additive
  • Dehumidification of oil-gas
  • Desiccation of ethylene, propylene, and ethanol
  • Purification of air
  • Separation of gas or liquid
  • Polysulfide and silicone systems
  • Protective agent for highly hygroscopic goods
  • Refrigerant desiccant
  • Coatings, Sealants & adhesive

For regeneration process, it requires the removal of adsorbed moisture, water and other provisions at a hot temperature of 250 to 450 degrees. This temperature depends when reached in purge. To avoid any kind of accidental moisture adsorption, such molecular sieves are required to keep in an air tight container before using it. The adsorbed species includes argon, SO2, CO2, carbon monoxide, C2H4, C3H6, C2H4, CH3CN2, CS2, CH3Br.
