| Chemical Name | 67% Antioxidant 168 + 33% Antioxidant 1010 |
| Introduction | Antioxidant Blend 215-a processing and long-term thermal stabilizer system-is a synergistic blend of antioxidant 168, an organo-phosphite of low volatility and particularly resistant to hydrolysis which protects during the polymer processing and antioxidant 1010, a hindered phenolic antioxidant that contributes synergistically to the processing stabilization and provides long-term thermal stability during service life. | ||
| Benefits | In the recommended applications it provides significant advantages, such as the maintenance of original melt flow, low color formation and improvement of long-term thermal stability. | ||
| Application | Antioxidant Blend 215 is used in polyolefins and olefin-copolymers such as polyethylene, polypropylene, polybutene and ethylene-vinylacetate copolymers. The blend can also be used in engineering plastics, styrene homo- and copolymers, polyurethanes, elastomers, adhesives, and other organic substrates. | ||
