Early causes for biodegradation of PVA/PVC tapes for audio recording Universiteit Gent
The degradation of magnetic tapes is one of the main threats to the survival of our collective audio heritage. Archives around the world, big and small, are all concerned with the same challenge, that of counteracting the natural decay of plastic compounds. This study investigates the biodegradation of poly(vinyl alcohol)/poly(vinyl chloride) (PVA/PVC) blends tapes, namely audio magnetic tapes, using the spectrophotometry (FTIR), scanning ...
