My high heat plastics cheat sheet – what you find in there: I tried to capture the most interesting and important material data and transformed it into a cheat sheet which allows you to have all in one infographic. It has three property sections (mechanical, thermal and processing) and represents the following polymer groups: • Polysulfones • Polyimides • Polyphylensulfides • Semi-aromatic Nylons • Polyaryletherketones • Liquid Crystal Polymers • Fluoropolymers The cheat sheet can be useful e.g. for a first comparison in the material selection phase.
