    Antioxidants Stabilizers Selection for Polyolefins (PP, PE)

    Antioxidants Stabilizers Selection for Polyolefins (PP, PE) Polymer degradation is a natural phenomenon that cannot be totally stopped. It tends to deteriorate the physical & mechanical like molecular weight, melt flow rate, appearance, processing and thermal stability properties of the polymer.

    BNX 1215 is a convenient blend of both a primary and secondary antioxidant. 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, and TPO's.

    PVC Stabilizers | Anti-Chalking Additives | Lubricants

    PVC THERMAL STABILIZERS . During high temperature processing operations, PVC is subject to thermal degradation by a dehydrochlorination process, resulting in undesired effects such as discoloration and cross-linking. This type of degradation can also take place during end use at elevated temperatures, for example in automotive applications.

    Polymer stabilizers

    Light stabilizer are used to inhibit polymer photo-oxidation, which is the combined result of the action of light and oxygen.Like autoxidation this is a free radical process, hence the antioxidants described above are effective inhibiting agents, however additional classes of additives are also beneficial, such as UV absorbers, quenchers of excited states and HALS.
