Applications

BNX 2777 is a convenient blend of both a primary and secondary antioxidant. This synergistic blend addresses a broad range of stabilization needs. The resistance to “gas fading” makes it ideal for use as a melt processing stabilizer in polyolefins such as polypropylene, polyethylene, polyolefin copolymers and blends, and TPO’s. BNX 2777 is also suitable for use in linear polyesters, high impact polystyrene, ABS, PVC, EPDM, nylon, acetals, and polyurethanes.

Guidelines for Use

Typical recommended loading concentrations in polyolefins and polystyrene range between 0.05% and 0.5%. BNX 2777 is also suitable for use in combination with 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.
