Benefos® 1626 is a phosphite type antioxidant of high phosphorous content. This secondary antioxidant provides excellent heat stability and reduction in polymer degradation during processing. Benefos® 1626 has good synergism when used with light stabilizers such as benzophenones and benzotriazoles.

Applications: This secondary antioxidant when combined with Mayzo's antioxidants, address a broad range of stabilization needs. Benefos® 1626 is particularly useful in polyolefins and olefin-copolymers such as polyethylene, polypropylene, polyesters as well as engineering thermoplastics, PVC, elastomers and adhesives. Benefos® 1626 can also be used in combination with UV absorbers and light stabilizers to provide enhanced performance.

Advantages:

• Extends performance of primary antioxidants (i.e. BNX® 1010 or BNX® 1076)

• Synergism when used with light stabilizers such as benzophenones and benzotriazoles.

• Improvement of long-term stability

• Maintenance of original melt flow

• Prevents discoloration

• Protects polymers from chain scission and crosslinking
