The Ethylene Glycols Panel (Panel) of the American Chemistry Council appreciates the opportunity to comment on the California Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) proposed Maximum Allowable Dose Level (MADL) for ethylene glycol (EG). Panel members include manufacturers of EG, which is used in many commercial and industrial applications including antifreez...

In this article, the reversible and irreversible thermo-mechanical time-dependent deformation of oriented polyethylene terephthalate film is studied. A mean-field model is used to simulate these effects along with the long-term creep behaviour, taking into account the underlying material microstructure and differences in constitutive behaviour of the phases. The material is modelled as an aggre...

Having established commercial applications of hot compacted products based on polypropylene we are now actively exploring other polymers to ascertain whether these can provide practical alternatives and in particular improvements in terms of certain physical properties. We have selected polyethylene (PE), poly (ethylene terephthalate) (PET) and nylon for comparative trials. For these materials,...

Single-use bioprocessing bags and bioreactors gained significant importance in the industry as they offer a number of advantages over traditional stainless steel solutions. However, there is continued concern that the plastic materials might release potentially toxic substances negatively impacting cell growth and product titers, or even compromise drug safety when using single-use bags for int...
