Constructed from breathable Tyvek (TM) on one side and clear PET film on the other, this uniquely designed pouch contains an indicating powder that absorbs corrosive sulfurous gases such as hydrogen sulfide and volatile mercaptans. As the pouch absorbs the corrosive gases the powder will change color from green to black notifying the user when replacement is needed. Corrosorber Pouch will not release the corrosive gases back into the atmosphere. The reaction is irreversible, eliminating any concern about post contamination.
Tyvek is a registered trademark of DuPont.
PACKAGING: 300 units per carton.
SERVICE LIFE: Up to 2 years under mildly sulfurous conditions or until color changes from green to black in more aggressive environments.
