short overview of some assays for the measurement of
scavenging activity assays are based on the ability of an antioxidant to scavenge stable free radicals. some of the most common antioxidant assays based on scavenging activity include orac, dpph, 2,2′-azinobis-(3-ethylbenzothiazole-6-sulphonate) (abts)/teac assay and n,n-dimethyl-p-phenylenediamine radical scavenging (dmpd) assay [31,32].

rubber antioxidant tmq (rd) (granular) dalian richon chem
view technical datasheet of rubber antioxidant tmq (rd) (granular). it is a 2, 2, 4-trimethyl-1, 2-dihydroquinoline polymer suitable for adhesive tape.
antioxidant tmq granular with high quality,antioxidant tmq granular provides superior protection as an antioxidant and process stabilizer for thermoplastic polymer applications. antioxidant tmq granular also protects from high-temperature-induced scorch for polyols, polyurethanes, and foam formulations.
breaking free from free radicals: harnessing the power of
massive production of the free radicals disrupts the system of antioxidant defense in the animal body thereby causing damage to cellular molecules (nucleic acid, lipids, protein, and cell membrane) which results to cell death or mutation that may give rise to abnormal cell division.
recent progress in the rubber antioxidants Rubber Auxiliary Agent,various external factors, including oxidative agents (such as oxygen), heavy metals, uv rays, ozone, mechanical stress, heat, and aggressive chemicals, etc., could accelerate rubber aging. this review mainly focused on thermo-oxidative aging because it is the most common aging type for rubbers.
- Can rubber antioxidants contain rare-earth ions?
- The recently reported rubber antioxidants containing rare-earth ions are summarized in Fig. 4, for instance, Sun et al. prepared a novel hindered phenol rare-earth complex (DTSm) (Fig. 4 f) by a simple and green method using 3,5-di-tert-butyl-4-hydroxybenzoic acid (DT) and samarium chloride hexahydrate (SmCl 3 ·6H 2 O) via coordination reaction.
- How to graft antioxidants on rubber filler?
- In brief, the solid-phase method to graft the antioxidant on rubber filler could reduce the use of organic solvent, and thus provide a green approach. Apart from silica, other fillers, such as graphene and halloysite nanotubes, were also widely used as a carrier to immobilize the antioxidants.
- Is there a good correlation between EC 50 / IC 50 and antioxidant concentration?
- A difficulty with proper estimation of the EC 50 /IC 50 which can result from the lack of a “good” correlation between the percent inhibition values and the EC 50 /IC 50 values with the applied antioxidant concentration (Bellik 2014).
