I’m currently working my way around a subject that requires more insight into polyurethane.
I wanted to know if there‘s any link between the smell (odor) of a polyurethane product (such as toys) and its toxicity.
Most toys as I know, if made by polyurethane, are cured using a chemical induced curing agent, either benzen, isocyanate or others. However, I haven’t find any researchs or study/ journal about the link between these curing agent and its (possible) toxicity pre and post curing.
I’m very curious to know if the smell that’s coming off a polyurethane toys is toxic or not, and if yes, what might have caused that smell?
i’d appreciate any answer or links to the research that might answer my questions. Thank you
Hương Đào Almost all polymers are in a solid state and are non-toxic. Volatile toxicants impart odor to polymer materials. Therefore, to obtain polymer materials for everyday use, the absence of volatile compounds in the plastic composition is required.
Hương Đào Thanks for your answer. I have a question: Are antioxidants considered volatile compounds?
Hương Đào Benchaoui Abdelmounaim If a substance has an odor, then it is volatile. Antioxidants can be toxic.
Hương Đào Oleg Novikov This means that if an antioxidant has a smell, it is volatile, and if it does not have a smell, then it is not or what.
Regarding toxicity, are industrial antioxidants toxic, or are there some that are toxic and some that are not, and how do we differentiate the toxic ones from the non-toxic ones?
Thank you very much
