Applications

• RIANOX® 1520 is an effective thermo-oxidative stabilizer in a wide range of solution polymerized, emulsion polymerized and thermoplastic elastomers including: BR, SBR, NBR, IR, SBS, and SIS as well as natural rubber.
• The antioxidant is effective both as a raw elastomer and compound stabilizer. It is also effective in
• various adhesive and sealant applications and latex applications.
• RIANOX® 1520 is unique in its ability to provide both processing and long-term heat aging stability used alone, at low levels and without costabilizers.
• Where necessary RIANOX® 1520 can be used with other additives such as secondary antioxidants, benzofuranone, light stabilizers and other functional stabilizers.
• The effectiveness of these products in a wide range of elastomers coupled with extensive food contact approvals makes RIANOX® 1520 an excellent choice where consolidation of antioxidant systems is desirable.
• In addition, the liquid, low viscosity nature of RIANOX® 1520 makes bulk delivery and storage very convenient.
