PUREstab B220 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 color formation and improvement of long-term thermal stability.
Applications & Uses

- Product Applications
PUREstab B220 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.
In Polyolefins the concentration levels of PUREstab B220 range typically between 0.1% and 0.25 %, depending on substrate and processing conditions. Typical recommended concentrations ranges between 0.05% and 0.5%. PUREstab B220 is also suitable for use in combination with hindered amine light stabilizers (HALS) and UV absorbers. The exact formulation to be used is dependent on the substrate, performance requirements, and other factors, and should be determined by the user based on testing to simulate actual conditions of use.
