Nylon 6, 6 is regarded as tough and ductile materials since it exhibit high tensile elongation to break and high drop weight impact strengths. However, under conditions of stress concentration such as in the presence of sharp notches or cracks, polyamides exhibit brittle failure. This property, evaluated as notched Izod or Charpy impact tests, indicates that unmodified polyamides exhibit relati...

The residual levels and migration behavior of volatile substances were detected using HS-GC/MS for acrylonitrile-butadiene-styrene copolymer (ABS) toys, thermoplastic elastomer toys, and rubber toys made from 1,3-butadiene and styrene found on the Japanese market. The maximum residual level of these volatile substances was 2600 μg/g of styrene in ABS toys. In particular, the levels of known car...

The management of end-of-life tires (ELTs) is one the main environmental issues that society faces nowadays. Recycling ELTs appears as feasible option for tackling problem, although their incorporation ground tire rubber (GTR) in other matrices limited due to poor compatibility. In this research, we report a successful combination cryo-grinding process with chemical treatment modifying surface ...

this study treats one important aspect of starch-filled rubber compounds which is their rheological behavior. starch-based sbr1712 masterbatches resulting from various formulations were prepared using a mini two roll mill and an internal mixer (plastograph brabender).the content in starch was varied from 0 to 50 phr. the effect of starch content on the rheological behavior was evaluated through...
