Molecular Sieve 3A/5A/13X/13X-APG/13X-HP/Li-X/CMS Molecular Sieve are so named because there are uniform pores inside the particles of molecular sieves, which can separate molecules of different sizes according to the size of the pores. Zhongci, as a professional production factory for more than 20 years, produces many types of zeolite molecular sieve adsorbents. Some of the more common molecular sieve types include Molecular Sieve 3A, Molecular Sieve 4A, Molecular Sieve 5A, Molecular Sieve 13X, Molecular Sieve 13X-APG, Molecular Sieve 13X-HP, Molecular Sieve Li-X, Carbon Molecular Sieve, Nay Molecular Sieve, XH-7/9 Molecular Sieve etc.
