Product Description:
Used primarily as a stabilizer in polyvinyl chloride (PVC) and other polymer systems, this compound helps prevent degradation caused by heat and ultraviolet (UV) light during processing and end-use. It acts as an antioxidant and chelates metal impurities that can catalyze polymer breakdown. Commonly found in rigid and flexible PVC applications such as pipes, cables, films, and coatings, it enhances long-term color and structural stability. Also employed in combination with other stabilizers like calcium-zinc systems to improve overall performance in environmentally sensitive applications where heavy metals are restricted. Its cyclic ester structure contributes to good compatibility and low volatility in polymer matrices.
