Used primarily as a stabilizer in polyvinyl chloride (PVC) plastics, this compound helps prevent degradation caused by heat and ultraviolet (UV) light during processing and in end-use applications. It is especially effective in flexible PVC products such as cables, flooring, films, and sheets where long-term stability and clarity are required. Its low volatility and good compatibility with plasticizers make it suitable for applications involving prolonged exposure to elevated temperatures. Additionally, it contributes to maintaining the color and mechanical properties of PVC over time, enhancing product durability in construction, automotive, and packaging industries.
