SamenvattingThe two primary strategies to preserve objects made of rubber are the removal of oxygen (anoxia) and the lowering of temperature. This paper describes a study in which the effects of those strategies were compared directly with each other.
Newly acquired elastic bands made of polyisoprene rubber were stored in common oxic and anoxic environments differing both in temperature and light conditions (daylight vs. darkness). After 5.5 years, visual changes, mechanical properties, chemical composition and off-gassing components were compared. Factors such as conservation effectiveness, cost and carbon footprint were considered during the evaluation. The results showed that cool dark storage is the preferred strategy for new rubber.
Keywords: rubber, low-oxygen, cold storage, energy use, cost-effectiveness, gas chromatography–mass spectrometry (GC–MS), Fourier transform infrared spectroscopy (FTIR), stress-strain testing
