This chemical is primarily utilized as a stabilizer in the production of polyvinyl chloride (PVC) materials. It enhances the thermal stability of PVC, preventing degradation during processing and extending the product's lifespan. Additionally, it is employed in the manufacturing of flexible PVC products, such as cables, flooring, and synthetic leather, where it improves resistance to heat and light. Its application also extends to coatings and adhesives, where it contributes to durability and performance under varying environmental conditions.
