Introduction
Molecular sieve 4A activated zeolite powder, or activated zeolite powder 4A, is obtained by calcining molecular sieve 4A zeolite powder at high temperature. It is the sodium form of the type A zeolite with a pore size of 4 angstroms (0.4 nm), and it exists as a white fine crystalline powder.
Due to its micron-sized powder form, high water adsorption capacity, and ion exchange capacity, activated zeolite powder 4A is applicable to occasions that require fast, deep drying or calcium ion control, such as polymer systems or coating systems, etc.
Activated zeolite 4A has the advantages of lower cost and higher water absorption efficiency compared to activated zeolite 3A. However, it may adsorb some polar organic substances. Therefore, type 4A molecular sieve activated powder has applications in a lot more areas, especially in the rubber and plastics industries.
