Molecular Sieve 4A

Absorbing water,methanol, hydrogen sulfide, sulfur dioxide, ethylene, propylene etc. for desiccant application.

Properties Molecular Sieve 4A:  
 

Pore size of molecular sieve 4A, mainly for absorbing water, methanol, hydrogen sulfide, sulfur dioxide, ethylene, propylene, does not adsorb any molecular larger than 4A (including propane).

 

According to the characteristics of industrial applications, the adsorption rate of the 4A molecular sieve we produce is much faster with  more regeneration times than any other elements.

It is one of the largest amount of desiccant application in chemical industry.

Conservation of molecular sieve 4A:

 

1. Room temperature, humidity <90%, non-expose to air;

2. Non-contact with water, acid and alkali.

3. Not to expose to the air directly.
