The pore size of 3Amolecular sieve is 3A.It 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.
