The Storage Length Evaluation of Rubber Sealing Components with Accelerated Thermal Ageing Tests

Rubber sealing components are significant proportion in evaluation of the storage length for production using it. It is necessary to determine and prolong the storage life of production that evaluated the storage length of rubber sealing components accurately. Based on artificial accelerated thermal ageing tests at five levels of temperature, conclude that the storage length of silicon rubber 3S-60 sealing components would be 11.6 years at 25°C and the confidence level of 95%. Validated this conclusion with nature weathering tests results at Jiangjin exposure field in two years, artificial accelerated thermal ageing tests presented here were available. It was illuminated that the storage length evaluation of rubber sealing components should be testified by nature weathering tests results effectually.
