Dibenzoylmethane
Dibenzoylmethane (DBM), identified by its CAS number 120-46-7, is a vital chemical additive that significantly enhances the performance and longevity of Polyvinyl Chloride (PVC) products. As a highly effective PVC heat stabilizer, it plays a crucial role in preventing thermal degradation during the high-temperature processing of PVC. DBM works by neutralizing hydrochloric acid (HCl) released during processing and by stabilizing the polymer chain, thus maintaining the polymer's molecular weight and preventing premature breakdown. This leads to a marked improvement in the initial coloration and transparency of PVC products.
