“…This modification in color of ZnPT-loaded material can be related to its extreme instability 12 accelerated by UV light resulting in photodegradation 26 . In SEBS compounds, color variation is normal and could be ascribed to degradation of styrene and conjugated bond sequences in the polymer backbone, hence becoming similar to stilbene (which is yellow) 28,29 . In the Standard sample, the global color (∆E) change after 96 h under UV light was of 2.4, results up to 2.0 are visually imperceptible.…”

The purpose of the present study was to evaluate the antimicrobial potential of styrene-ethylene/ butylene-styrene based thermoplastic elastomers (TPE) incorporated with zinc pyrithione (ZnPT) and silver nanoparticles (AgNano). Japan Industrial Standard was applied to evaluate the antimicrobial potential of incorporated TPE compounds against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). Antifungal action was evaluated against Aspergillus niger, Candida albicans and Cladosporium cladosporioides. Samples prepared with ZnPT eliminated 99.9% of the E. coli and 99.7 % of the S. aureus population, and presented an inhibition zone in the fungal assay. Samples prepared with AgNano eliminated 99.7% of the E. coli and 95.5 % of the S. aureus population. There was no inhibition zone in samples containing AgNano; however, these samples did not present fungal growth on their surfaces. TPE samples containing ZnPT showed biocidal activity against the microorganisms tested and can be used to develop antimicrobial products.

“…Some properties of SBR such as abrasive resistance, heat resistance, and aging resistance are superior to those of NR, and thus SBR has replaced NR partially in many fields. However, due to the instability of double bonds in SBR to ultraviolet, heat, and oxygen, aging processes like chain scission, chain crossing, and oxidization take place easily when the SBR products are in use just like other styrene-butadiene copolymers [9][10][11][12][13][14][15][16].…”

“…The generation of free radicals causing undesirable reactions of the double bonds in PB segment makes its degradation, while various antioxidants are available to reduce the degradation, such as the use of hindered phenols to scavenge the free radicals and the use of phosphites to decompose the hydroperoxides. [11][12][13] In this article, the variation of reactive groups during the process of thermal oxidation was investigated by Fourier transform infrared and differential scanning calorimetry. In particular, the effect of two kinds of antioxidants on improving the aging resistance of SBS was validated by different methods.…”

Thermal oxidation process of styrene-butadiene-styrene (SBS) copolymer was studied by using a variety of analytical and spectroscopic methods including thermal analysis, dynamic mechanical analysis and FTIR spectroscopy. The experimental results indicate that the thermal oxidation process of SBS is a free radical self-catalyzed reaction containing four steps (initiation, growth, transfer, and termination of the chain) with both crosslinking and scission and the latter is confirmed to be the main process. The antioxidants 1010 as scavenger of free radicals and 168 acting decomposition of hydroperoxides were used to improve the oxidation aging resistance of SBS copolymer. It has been found that synergic effect of 1010 and 168 may be the best in practice and 0.2 wt % 1010 þ 0.4 wt % 168 can effectively prevent SBS from the thermal oxidation at certain temperature. Furthermore, the aging resistance of the SBS-modified asphalt was improved by addition of complex antioxidants.
