Rubber Rings Wholesaler shares that aging is one of the main causes of rubber performance damage. Due to the different formulations and use conditions of the products, the aging process is different, so it is necessary to measure and evaluate through the aging test to assess the degree of rubber aging and its impact on performance. The aging test is a test method and test method used to evaluate the changes in rubber performance before and after a certain period of time (generally, the performance is reduced or deteriorated) under external conditions. Commonly used rubber aging test methods are as follows.

Oven heating aging test Referred to as heat aging test, it is currently the most widely used method. The test equipment used was a heating oven. The heating temperature (usually 70 and 100) and time (usually 72 and 144h) can be set. The test piece is hung on the rotating film holder in the box. After the test, the test piece is taken out, its performance is measured, and compared with the data before aging, the aging coefficient is calculated, and the degree of damage reduction is measured. For example, the tensile strength of a rubber compound before thermal aging is 20MPa, and after thermal aging is reduced to 12 MPa, the aging coefficient is 0.6.
