Grain coal


It is a granulated product presented as cylindrical pellets based on natural clays which have been extruded together with potassium permangante (KMnO4) as active principle. The KMnO4 in CARB FORMALDEHYDES is responsible for the removal of the target gases, principally ethylene and formaldehyde, thanks to a chemical reaction on the active surface of the absorbent.
