When I need to glue difficult plastics, or anything else unusual, I'll start by browsing through the McMaster adhesives section. They have filters for materials – including HDPE, polystyrene, PTFE – so it's easy to find a glue that should work. They list brand and model # so I'll track down spec sheets or instructions from the manufacturer, or see if someone's put up a review on YouTube.
