Polyvinyl Chloride (PVC) is one of the most widely used plastics globally, found in everything from construction materials like window profiles and pipes to flooring and packaging films. However, PVC is inherently sensitive to UV radiation, which can lead to rapid degradation, resulting in discoloration (yellowing and browning), surface chalking, and loss of mechanical properties. To combat this, effective UV stabilizers are essential, and UV Absorber UV-P (CAS 2440-22-4) is a highly regarded solution.

Understanding PVC's UV Sensitivity

The degradation of PVC under UV exposure is a complex process involving dehydrochlorination and the formation of conjugated polyene sequences. These sequences act as chromophores, absorbing visible light and causing the characteristic yellowing. Further exposure can lead to chain scission and cross-linking, resulting in embrittlement and surface deterioration. Therefore, incorporating UV absorbers is a critical step in ensuring the durability and aesthetic appeal of PVC products, especially those intended for outdoor use.
