Adhesives consist of organic polymers, and therefore are in general highly sensitive towards oxidative decay (reactions include chain scission, loss of end groups, cross-linking). Thermal conditions during the initial polymerization (for synthetic organic polymers) and during the thermal processing are particularly harmful and lead to thermo-oxidative decay. To circumvent this, polymers are generally stabilized for processing.

Additional treatment with antioxidants, UV absorbers, HALS etc. are used to prevent oxidative decay caused by external factors such temperature, light exposure, humidity etc. These treatments are crucial to ensure the requested service lifetime of polymers, in particular for long-term application and extreme conditions (outdoor applications, motors, isolation of cables). The technology of ACL Instruments allows a very precise characterization of the efficiency of such stabilizing treatments, especially since the application conditions can be very closely simulated. This permits optimization in regard to both the composition and quantity of stabilizing system used. The specific life expectancy of individual product formulations under given application conditions can be accurately predicted using isoconversional analysis of the oxidative kinetics.
