Napalm-like fiery substances have been used since early Greek times for war purposes. Is Gorilla Glue safe for Styrofoam? p-Cymene and polystyrene can be recovered almost quantitatively from the polystyrene solution by simple steam distillation. We have only tried with traditional chemical products and the results are good but very toxic and that is not what we are looking for. If everyone just did this step, and digested down all the packing styrofoam they get we could save a bunch of landfill space. The favorable solubility of polystyrene into p-cymene can be explained by the solubility parameter. For a faster drying but still low toxicity solvent, I'm also having good luck with ethyl acetate. Reuse is the act of extending a products life. It can be molded and formed. When the polystyrene dissolves in the acetone, the air in the foam is released. (fewer bubbles in more thick/dry stock). 1 year ago Might be good for just strictly commercial use, this may also vary by formulation, D-limonene: works great on plain white ps, will dissolve quite a lot per oz, nice smell, not known to be toxic, leaves the ps very clear (sometimes a slight yellowing) virtually no bubbles, long glass transition. This is also the first step in commercial recycling too. Is that "plastic" safe to use? Polystyrene is an aromatic hydrocarbon, it has several complicated double covalent bonds and is a chain of styrene molecules (C6H5CH=CH2) which is very unsaturated.
