CHINESE PLASTIC AND NOT......... CLASSIC VERY STRONG SMELL. I wanted to write these two lines because online I see many people asking about it. The question is always this (HOW DO I GET RID OF THE PETROL SMELL OR ANYWAY THE BAD SMELL OF CHINESE PLASTIC) The answer is very complex and has to do with polymer chemistry, which is why I’m writing these two lines to clear up any doubts for users. 1) Saying plastic in general is very limited; usually they are POLYAMIDES OR POLYESTERS (SHOES, BAGS, WAIST BAGS) For example, I have a small bag I bought in a very cheap shop (Italian, not online) that sold me a bag imported from China with the classic smell. I always smell everything before buying it, and if it smells I don’t take it. But this time I fell for it. 2) POLYESTER is the most used one. A polymer is a molecule with a high molecular weight synthesized by linking together a repeating unit. For example, PET is a polyester. polyethylene terephthalate. Polyesters are such a huge family of polymers that you can’t know what the waist bag or the bag or the shoes are actually made of. It’s like saying I ate some fruit for dinner without specifying which fruit in particular. 3) PLASTICIZERS Now we get to the heart of the matter: polymers on their own are very often rigid, and to be processed they need to be more malleable or ductile.That’s where plasticizers come in, and there are different types. What does a plasticizer do? I’ll give an example. Reinforced concrete is made of cement powder + gravel. If instead of gravel I put in cork balls, these have a very low density and interrupt the compaction of the cement; once dry, this reinforced concrete becomes weaker.Broadly speaking, it works like that, but the mechanism is obviously different. The plasticizer reduces the crystallinity of a polymer (+ crystalline means + packing), reducing the level of packing. This makes the polymer more shapeable.5) As I said before, plasticizers come in many types, and there are also solvents that act as plasticizers. e.g. the blue plastic basins (bought in Italy, I mean) have a bit of a "plastic" smell because the plasticizers used in those products are legal and certified. In China they still use illegal and above all less durable products.6) The more the plastic smells, the less it lasts, because it means the plasticizer is sublimating from the product. So the plastic loses elasticity, becomes rigid, and breaks. Old plastic basins break like glass after one or two years of use or if they are exposed to the sun for long periods.It’s possible to reduce the smell of Chinese plastic by leaving the products out in the air for a while, but the faster the plasticizer sublimates, the sooner the product gets ruined. So, to avoid getting poisoned, don’t buy this kind of product—avoid it like the plague. There is no way to completely get rid of the smell because this smell is a result of industrial production during the synthesis phase of the polymer itself, intrinsic to the molecule......
