• Cyanoacrylate (superglue) or Epoxy (Araldite) will both work on some plastics, surface preparation is the key. Some plastics are a bugger to glue with anything, PTFE (Teflon) being the obvious one.

    With a mechanical key, and microfibres, proper epoxy (not araldite) wil stick anything to anything. I've used it to bond nylon sprockets to metal axles, and it's take a massive amount of torque and power without the join failing.
