ANTIOXIDANT-YDI520L is a multifunctional liquid phenolic antioxidant with highly effective stabilization for organic materials such as elastomers, plastics, adhesives sealants, oils and lubricants. It protects these materials against thermo-oxidative degradation. It can be applied for emulsion and solution polymerized elastomers such as BR, SBR, NBR, SBS, and others. ANTIOXIDANT-YD1520L is effective both as a raw elastomer and compound stabilizer. It also effectively protects various adhesive, sealant, and latex applications. It is non-discoloring, non-staining, low in volatility, and stable to light and heat. It is not recommended for odor sensitive hot melt adhesives or their raw materials. ANTIOXIDANT-YDI520L can be used alone at low levels without co-stabilizers to provide both

processing and long-terms heat aging stability. If needed, it also can be used with other additives such as secondary antioxidants, benzofuranone, light stabilizers, and other functional stabilizers. The effectiveness of this product used in a wide range of elastomers is exceptional along with extensive food contact approvals.
