This chemical is primarily used as a stabilizer in the production of polyvinyl chloride (PVC) materials. It helps to prevent degradation of PVC when exposed to heat, light, or mechanical stress during processing and use. By enhancing the thermal stability of PVC, it ensures the material retains its desired properties, such as flexibility and durability, in applications like construction materials, automotive parts, and packaging. Additionally, it is employed in specialized coatings and adhesives where stability under harsh conditions is required. Its role in these industries contributes to the longevity and performance of the final products.
