Intercept Anti-corrosion Sheet for artefact storage
Corrosion intercept is a copper loaded polyethylene film used to scavenge nitrides, sulphides and chlorides. The technology has also been developed into a wide range of products including copper loaded foams and canvas.
Copper is a highly reactive metal and will react with contaminating gaseous ions preferentially. The copper in the plastic behaves similarly to a sacrificial anode.
