Molecular sieve 4A

Zeolite type 4A, or simply zeolite 4A, is a synthetic, colorless aluminosilicate. In its hydrated sodium form, it has the molecular formula Na₁₂((AlO₂)₁₂(SiO₂)₁₂) · 27 H₂O and a clearly defined pore size of approximately 4 Å (0.4 nm). Zeolite 4A can selectively absorb small polar molecules, especially water. Larger molecules such as alcohols, nitrogen, oxygen, or hydrocarbons, on the other hand, can hardly penetrate it and are largely excluded.

Our product is used in industry for various industrial applications, particularly in plant engineering.

Zeolite 4A has a remarkable story: Its exceptional properties have triggered an ecological revolution, as it has successfully replaced environmentally harmful ingredients in detergents.

Zeolite 4A is available in several forms, most commonly in spherical form. This molecular sieve can be used in adsorption dryers, compressed air dryers, and for gas treatment.

Other applications include the detergent industry, water treatment, flue gas drying, and the production of heat stabilizers for PVC, etc.
