Accelerated Ageing
Posted on 21/12/2018 Category:
Heat ageing is widely used as a method of evaluating long term ageing properties. Hardness and dumbbell type tensile test pieces are placed in an air circulating oven for a specific period of time at a given temperature (e.g. 7 days at 70°C). The properties of the rubber are then tested and compared with the properties before ageing. The percentage retained for each property is recorded.
