Product Introduction

Zeolite Molecular Sieve 3A is a potassium-type aluminosilicate (K₂O·Al₂O₃·2SiO₂·xH₂O) synthetic zeolite adsorbent with a standard pore size of 3 Å (0.3 nm), commonly found in spherical or strip-shaped particles. It is suitable for deep drying of natural gas, petrochemical, and refrigeration systems.
