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.
What is the most efficient antioxidant or heat stabilizer
Finally, I will say that for instance it is difficult to say what is the most efficient antioxidant/thermal stabilizer for PLA/PA6 blends…but during the time we will receive the best answers.
Processing & Thermal Stabilizers Archives - Van Horn, Metz
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.
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.
POLYETHYLENE (Stabilization and Compounding)
Ethyl Corp. released a new fluorophosphonite antioxidant system known as Ethanox 398, which exhibits high thermal stability (up to 287 °C) and outstanding resistance to charring.
Stabilization effect of lignin in natural rubber | Request PDF
Lignin can act as a stabilizer preventing polymer aging due to its antioxidant activity  . Lignin has the advantage of being a bio-based compound and can be effectively used as carbon
