PVC stabilizer plays an important role in the production and application of PVC materials, which can improve the oxidation resistance, thermal stability and light stability of PVC materials and prevent the decomposition and degradation of materials. At the same time, it can also improve the processability, flexibility and impact resistance of PVC materials, and improve the quality and service life of products. In the future development, people will continue to develop new PVC stabilizers to meet the needs of PVC materials in different fields.
