QUALITY & VALUE
Materials (mainly vulcanized rubber) exposed to ozone medium for a certain period of time will produce specific aging phenomena, such as: cracking, loss of light, discoloration and other changes on the surface of the material; Therefore, the test samples were exposed to a closed chamber containing constant ozone concentration and constant temperature, and the test samples were tested for aging according to the predetermined time and specific conditions. The ozone aging resistance of the test samples was evaluated by the degree of surface cracking or other changes in performance.

? Business Challenges
1. How do you know whether the material you produce will achieve the desired performance after a certain period of time when it needs to be used in outdoor conditions?
2. Which test conditions for ozone aging test can best simulate the actual use environment of the product?
3. Which kind of formulation can be used to improve the ozone aging resistance of the product? What is the relationship between the formulation, dosage and the final product performance?
