There is a lot of misinformation concerning the toxicity of plastics and it's important to note that this is a complex issue. The very nature of plastics means there are toxicity impacts associated with their manufacture, use and disposal, but that doesn't necessarily mean all plastics represent a risk to your personal health or that of the environment. The key issue to understand is the circumstances where plastic is likely to release toxic chemicals and where the wrong type of plastic is& ...

Leaching of additives and residual monomers from plastic pellets has been shown in a laboratory experiment where virgin plastic pellets made of polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC) and high-density polyethylene (HDPE) were kept in artificial seawater for 24 hours. Leachable components were found in all of the plastics except polypropylene. The leached compounds from PVC were not identified, but from the other plastic types& ...

The main objective of the present study is to investigate how the thermal, rheological, mechanical and cytotoxicity behavior of high density polyethylene (HDPE) can be changed by the addition of graphite nano particles (GNPs) at different contents. The HDPE/GNPs composites were prepared using melt blending in a co-rotating intermeshing twin screw extruder. The in vitro tests results showed that the original material (HDPE) and all HDPE/GNPs composites do not& ...
