Application
Antioxidant B 215 is used in polyolefins and olefin-copolymers such as polyethylene, polypropylene, polybutene and ethylene-vinylacetate copolymers. The blend can also be used in other polymers such as engineering plastics, styrene homo- and copolymers, polyurethanes, elastomers, adhesives, and other organic substrates. Antioxidant B 215 can be used in combination with light stabilizers.

Antioxidant B 215 is a convenient blend addressing a range of stabilization needs. In the recommended applications Antioxidant B 215 provies significant advantages, such as

  1. Maintenance of original melt flow
  2. Low color formation
  3. Improvement of long-term thermal stability

Antioxidant 168 - an organophosphate of low volatility and particularly resistant to hydrolysis-protects during processing organic polymers which are prone to oxidation. Antioxidant 1010 - a hindered phenolic antioxidant – contributes synergistically to the polymer’s stabilization during processing and provides long-term thermal stability by preventing thermo-oxidative degradation during service life.
