Morning All, While I wait for machines to build, I have been melting in my oven to form plastics into molds. I have been using cookie sheets with either parchment paper or silicone baking sheets to prevent sticking. However, it seems that sometimes the HDPE sticks fiercely to either the silicone or the parchment paper, and other times it doesn't stick at all. Does anyoen else have experience with ideal temperatures for HDPE to melt together but not stick to silicone? It has also seemed that Polypropylene (PP) sticks like crazy at any temp I have tried. any suggestions there? Thanks!
