4A Zeolite Powder CAS 1318-02-1
4A Zeolite Powder (CAS 1318-02-1) is a synthetic sodium aluminosilicate, a white powder with pores about 4 angstroms across. The crystal exchanges calcium and magnesium and adsorbs molecules small enough to enter the pores. Detergent plants use it as a builder to soften water and carry surfactants. It also serves desiccants, water treatment, petrochemical separation and plastic additives. UATChem supplies detergent and activated grades in woven bags and ton bags, with COA, TDS and SDS on request.

What 4A Zeolite Powder Is
4A Zeolite Powder is the sodium form of zeolite A, a crystalline aluminosilicate, CAS 1318-02-1, sold as powder. The crystal holds pores about 4 angstroms wide, and sodium ions exchange with calcium and magnesium in water. Small molecules enter and adsorb, larger ones stay outside. In detergents it softens water and carries surfactants, and activated form serves drying and separation. UATChem supplies it, with exchange and adsorption on COA, TDS.
Detergent, Drying, Water and Separation Uses
- Detergent builder. It softens water and carries surfactants in powder and liquid detergents, paired with sodium metasilicate.
- Desiccants. The activated powder is formed into 4A molecular sieve desiccants for gases and liquids.
- Water treatment. It softens water and removes heavy metal ions by ion exchange.
- Petrochemical and plastics. It serves adsorption separation and PVC and plastic additives.

- Samples are available for evaluation. To quote, UATChem needs the grade, quantity, packing and destination port.
FAQ
Q: What is 4A zeolite powder used for?
A: It softens water as a detergent builder and serves desiccants, water treatment, petrochemical separation and plastics.
Q: Why is 4A zeolite used in detergents?
A: It exchanges calcium and magnesium ions to soften water, and the powder carries liquid surfactants and aids powder flow.
Q: How is 4A zeolite powder packed?
A: UATChem supplies the white powder in 25 or 50 kg woven bags and FIBC ton bags, kept sealed and dry, with COA, TDS and SDS.
Q: Is 4A zeolite a molecular sieve?
A: Yes, the pores are about 4 angstroms wide and adsorb small molecules, so the powder forms 4A molecular sieve desiccants.
