within the scope of my master thesis it´s necessary to fabricate my own PLA with high temperature resistant properties. Do you have any ideas what the composition of such a filament could be? Or in other words, what do I have to add in order to guarantee high temperature resistant properties?
Better than talcum a high aspect ratio filler like glass. Also increasing crystallization is good, talcum can help but it depends on how slow cools the polymer and there must be better options. Another one is to branch the polymer or blend it with another one.
