After a chat with
@Hooli I recently repaired a set of clock internals .
No glue or super glue would touch the plastics.
I then got this that matches the same type of plastic the clocks are made if and it worked really well.
It leaves a white deposit when dry but holds as if they'd never broken.
Here's the link for it .

Hope it helps any one needing it .

I'll be trying it myself at some point, cheers Seth.
Yep I'm pretty sure the plastic used is a Polyethylene.
QuoteAutomotive Applications: Polypropylene is widely used in automotive parts because of its low cost, weldability, and mechanical properties. It can mostly be found in battery cases and trays, bumpers, fender liners, interior trim, instrumental panels and door trims.
Technically you don't 'glue' PE, you
bond it.
Many glues won't work because... reasons.
If you want to know what reasons, prepare yourself for boring science:
QuotePolyethylene is a non-polar polymer, because its chains contain only -CH2- groups. For PE bonding is necessary to increase its polarity and/or hydrophilicity. This aim can be achieved by surface activation of PE surface by radio-frequency discharge plasma or by barrier [or corona] discharge plasma in air or in oxygen, Subsequently we can bond PE using selected adhesives [e.g. epoxies, polyurethanes, polyacryacrylates]. Another method of bonding polyethylene is using an adhesion promoter [primer] that increases the polarity of the PE surface, e.g. chlorinated polyethylene dissolved in organic solvent [xylene]. In addition, a number of titanium, chromium-based primers as well as water-soluble adhesion promoters can be used for thin layer creation on PE surface before bonding.
