3A molecular sieve
The pore size of 3A molecular sieve is 3A. It mainly adsorbs water and does not adsorb any molecular larger than 3A. According to the industrial application specialties, we endue our products with the characters of higher adsorption speed, stronger crushing and anti-contaminative resistance, more cyclic times and longer work-span. All these advantages have made it come to be the most essential and necessary desiccant in the fields of the deep drying ,refinery polymerization for cracked gasses ,ethylene ,propylene and any other non-acidic gasses of liquids in petroleum and chemical industrials.

4A molecular sieve
The pore size for 4A molecular sieve is 4A. It is mainly used to adsorb water, methanol, ethanol, sulfureted hydrogen, carbon dioxide, ethylene, propylene, and does not adsorb any larger molecular than 4A include propane. Its selective water adsorption is higher than any other molecules. And it is the most common used desiccant in industrials.

Generation and purification of argon
Static dehydration of electronic element, pharmaceutical and unstable materials
Desiccant for paint, dope and foul
Packing：
25kg carbon box; 55Gallon iron drum.
Attention:

5A molecular sieve
The pore size for 5A molecular sieve is about 5A. It can adsorb all kinds of molecules smaller than this size. It is mainly used in separation of the normal and isomerous alkane; pressure swing adsorption (PSA) for gases; co-adsorption of moisture and carbon dioxide. Based on the industrial application specialties, we have produced out our own PSA molecular sieve products, which have better selective adsorb ability and more rapid adsorption speed, being the elaborated products, it could suitable for gases generation and concentration PSA plants of any sizes and any types in the world.
