Introduction

Zeolite molecular sieve 3A is a crystalline aluminosilicate, also known as zeolite 3A. It is the potassium form of type A zeolite, with a pore size of approximately 3 angstroms (0.3 nm). Molecules with a kinetic diameter smaller than 3 angstroms will be adsorbed by type 3A molecular sieve; otherwise, be excluded.

Zeolite molecular sieve 3A will exclude most molecules except water, making it very selective. And it can be made into beads or strips, which are widely used in ethanol dehydration, natural gas dehydration, refrigerant dehydration, insulating glass production, general moisture removal, etc.

Type 3A molecular sieve, with its precise pore size, high-temperature resistance, and long service life, has become the preferred adsorbent in deep dehydration applications, especially in the petrochemical, pharmaceutical, and high-purity gas processing industries where zero co-adsorption is required.
