RIANOX DLTP
Product Features
A sulfur-containing thioester secondary antioxidant that decomposes and neutralizes hydroperoxides formed by auto-oxidation of polymers during processing and long-term heat aging. Lower molecular weight than RIANOX® DSTP, offering better compatibility and easier dispersion in polymer systems. Widely used as a synergist with hindered phenolic primary antioxidants to deliver excellent long-term thermal stability across polyolefins, ABS, polyester, and polyamide applications.
