Rubber and plastic additives can effectively improve yellowing

The yellowing of rubber and plastic products under the long-term irradiation of natural sunlight and ultraviolet or under the action of heat, oxygen, stress, micro moisture, impurities and improper process is called yellowing. There is bond energy between the bonds of polymer macromolecules. When the energy provided is greater than the bond energy, the molecular chain is easy to produce active center, which will cause the gradual degradation of polymer in the process of use and storage, leading to yellowing.
