Hindered phenolic antioxidants as heat-oxygen stabilizers for HDPE

One of the most used primary family of antioxidants in industry is the very effective hindered phenolic antioxidants(e.g., Irganox 1010, Irganox 1330, Irganox1024, Irganox3114), which have good pollution-free and non-discoloring properties compared with the toxicity and discoloration of amine antioxidants.12-15 The long-term heat-oxygen stabilit...

Perspectives on yellowing in the degradation of polymer materials

Phenolic antioxidants are primary antioxidants and are classified chemically depending upon the number of phenolic groups in the molecule. Phenolic antioxidants act as a H-donors and are most widely used in polyolefins but with extended functionality in many other polymer systems inclusive of the aromatics.

Structure¨Cproperty relationships: phenolic antioxidants with high

The most broadly used primary antioxidants are hindered phenolics. Phenolic antioxidants have traditionally been based on 2,6-di- t -butyl-4-methylphenol (BHT). This functional moiety has been incorporated into larger molecules affording products with lower volatility or greater polymer compatibility.

Hindered phenolic antioxidants as heat-oxygen stabilizers for HDPE

In the presence of oxygen, degradation occurs already at ambient temperatures and the oxidation rate is considerably enhanced with increasing temperatures. 7¨C9 Among all kinds of methods to increase the heat-oxygen stability of polyethylene, the addition of antioxidants is an effective way to prolong the life of polyethylene. 10,11 Antioxidants can be classified as primary and secondary

Antioxidants: Classification, Natural Sources, Activity/Capacity

Primary antioxidants actively inhibit oxidation reactions by scavenging ROS/RNS, while secondary antioxidants act indirectly through chelation of transition metal (iron) ions [83,84] and other specific actions such as anti-inflammatory, induction of protective factors, inhibition of NADPH oxidase (nicotinamide adenine dinucleotide phosphate oxidase), inhibition of xanthine oxidase, and
