Benefos 1680 is a highly effective processing stabilizer in polyolefins, including polyethylene, polypropylene, polybutene, and in olefin copolymers such as EVA. It is also recommended for use in other polymers such as polyamides, polycarbonates, polyesters, polyurethanes, styrenic polymers, elastomers, adhesives, sealants, lubricants, and many other organic substrates.
- Guidelines for Use
Recommended loading concentrations range between 0.02% and 0.2% in polyolefins and between 0.05% and 0.25% in other substrates. Combinations of Benefos 1680 with phenolic primary antioxidants (BNX 1010, BNX 1076, and others) often show synergistic performance. Benefos 1680 is also suitable for use in combination with other antioxidants (for example thioethers) and light stabilizers, including hindered amine light stabilizers (HALS), UV absorbers, and benzoates. 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.
