MION AK-22
MION AK-22 is a weak-base fibrous anion-exchanger with three-dimensional cross-linked structure.
It is widely applied in vent filters for air purification from gases and vapors of acid nature, in masks for respiratory protection from vapors of acids and acid gases. Cloth made of MION AK-22 is used for special acid-protective clothes.
