Heat stabilizer Anti-aging performance
Release time:
2024-04-16
The anti-aging properties of PVC stabilizers are expressed through the anti-aging properties of PVC profiles. The anti-aging performance of PVC stabilizers in PVC profiles is manifested in two aspects, on the one hand, to ensure the thermal stability of the PVC molecular chain during thermal mixing and processing, and on the other hand, to ensure the thermal stability of the PVC molecular chain during the use of PVC profiles. To achieve these two aspects, the anti-aging performance of the stabilizer itself is particularly important. If the anti-aging performance of the PVC stabilizer is not good, the resulting color-changing molecules will cause the decomposition of the PVC molecular chain, which will not only prevent the decomposition of the PVC resin, but will accelerate the aging rate of the PVC resin. Therefore, evaluating the anti-aging performance of the PVC stabilizer itself is an important prerequisite for ensuring the anti-aging performance of the PVC profile. The evaluation content of the stabilizer: itself should have good thermal stability, light stability, in the thermal processing, preservation and use of the process does not change color, not colored. Here, we can also take the following four test methods to evaluate the anti-aging properties of the stabilizer: 1, PVC stabilizer itself outdoor sunlight; 2, PVC dry mix static thermal stability time; 3, PVC dry mix outdoor sunlight; 4, PVC profile artificial light aging irradiation test.
