Used primarily as a stabilizer in polyvinyl chloride (PVC) plastics, this compound helps prevent degradation during processing and extends the lifespan of PVC products. It is especially effective in maintaining thermal and light stability, making it suitable for use in outdoor building materials, cables, and films. Its low volatility and good compatibility with PVC resins allow for durable performance under varying environmental conditions. Additionally, it finds application in adhesives and sealants where long-term flexibility and resistance to aging are required.
