Material composition of Invisalign.

I will try to be as specific as possible from the Invisalign MSDS (material safety sheet).  Invisalign aligners are made of mostly Polyurethane from methylene diphenyl diisocyanate and 1,6-hexanediol.  What this really means is that its a medical grade polymer or plastic with some additives that change the properties of the material making it clear, strong, thin and flexible.  An ideal material to use in the oral cavity as it is hypo-allergic, inert and biologically stable.
