Product Description
Antioxidant B 215 (AO B215) - a processing and long-term thermal stabilizer system - is a synergistic blend of Antioxidant 168 (AO 168), an organo-phosphite of low volatility and particularly resistant to hydrolysis which protects during the polymer processing and Antioxidant 1010 (AO 1010)a hindered phenolic antioxidant that contributes synergistically to the processing stabilization and provides long-term thermal stability during service life.
Features & Benefits:
- Antioxidant B 215 (AO B215)is a convenient blend addressing a range of stabilization needs.
- This synergistic blend addresses a broad range of stabilization needs.
- The relatively high phosphite content of the blend makes it ideal for use as a melt processing stabilizer in polyolefins such as polypropylene, polyethylene, polyolefin copolymers and blends.
- It provides significant advantages, such as the maintenance of original melt flow, low colour formation and improvement of long-term thermal stability.
Applications:
- Antioxidant B 215 (AO B215)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.
Handling & Safety:In accordance with good industrial practice, handle with care and avoid unnecessary personal contact. Avoid continuous or repetitive breathing of dust. Use only with adequate ventilation. Avoid dust formation and ignition sources. For more detailed information please refer to the material safety data sheet.
Storage:This product may be stored in a sealed container. Containers should be kept tightly closed when not in use and stored in a cool, dry place.
Optimizing Polyolefin StabilityAntioxidant B 215 offers advanced stabilization for polyolefin materials. When used at recommended concentrations (0.05% to 0.5%), it effectively minimizes polymer degradation due to heat and processing, extending product lifespan. AO B215 can be used in combination with HALS and UV absorbers for even greater protection against light and heat.
Purity and Formulation ConfidenceWith 99.9% purity, AO B215 stands out for its consistent quality and efficacy. Composed of Antioxidant 168 and Antioxidant 1010 in a precise 2:1 ratio, it comes as a free-flowing, white crystalline powder. The blends molecular weights646.9 g/mol for Antioxidant 168 and 1178 g/mol for Antioxidant 1010ensure predictable performance.
FAQs of Antioxidant B 215 (AO B215):
Q: How should Antioxidant B 215 be used in polyolefin applications?
A: The recommended concentration of Antioxidant B 215 in polyolefins ranges from 0.1% to 0.25%, depending on the substrate and processing conditions.
