Rianox 1790

Rianox 1790 is a high performance, sterically hindered phenolic antioxidant f the trisphenol class with a cyanuric acid central moiety. RIANOX 1790 is especially suited for polyurethane, polypropylene, polyester and polyamide fibers where it provides at low dosage. The performance benefit of RIANOX 1790 includes the minimal color contribution, good solubility/migration balance and excellent compatibility with light stabilizer and secondary antioxidants, e.g. RIANOX DLTP/DSTP. In addition, RIANOX 1790 has a high molecular weight, which results in low volatility and good extraction resistance. In molding applications it is particularly recommended for filled systems where extraction resistance is an issue.
