Product details:
4A molecular sieve is an alkali alumino silicate. It is the sodium form of the Type A crystal structure. 4A molecular sieve has an effective pore opening of about 4 angstroms (0.4 nm). 4A molecular sieve will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger. Such absorbable molecules include simple gas molecules such as oxygen, nitrogen, carbon dioxide and straight chain hydrocarbons. Branched chain hydrocarbons and aromatics are excluded. These 4A Molecular Sieve Beads are specially designed for Vehicle Break System due to their high strength.
