Glue for plastics - recommendations
Discussion
What's the best glue for plastics these days?
Good old Loctite Superglue is pretty poor based on my recent experience.
The last stuff I bought was this : https://shop.ct1.com/gb/superfast-plus-50ml
and it worked well but the bottle nozzle just blocked up with hardened glue and it became too awkward to use.
Any alternatives?

I used some super glue all plastics on an admittedly tiny workpiece recently and got an excellent bond, really impressed. Was PP/PE so was expecting difficulty. It comes with an "activator pen" which appears to attack the plastic's surface enabling a bond with the second part which may or may not just be regular super glue. Parts must be tight fitting (superglue doesn't fill) and I keyed both surfaces with wet&dry. Pen/glue probably won't keep, usual story.

It depends on the plastic! You need the right type for the job.
Some things use solvents to weld them, others can need specialist types or just won't glue at all.
it for a fridge door - one of the moulded lugs that the bottle shelf slides into is coming away from the door lining....Some things use solvents to weld them, others can need specialist types or just won't glue at all.

Could be ABS or polypropylene or maybe polystyrene, and each of those has a different best option.
any way of determining what type of plastic it is? Acetone will melt/weld ABS (so works to put it back together) and it'll melt polystyrene too, but won't touch polypropylene.

Vacuum formed liner parts are usually polystyrene, and all the parts might be marked with the plastic type for recycling.

brilliant - thanks will check the recycling infoAcetone will melt/weld ABS (so works to put it back together) and it'll melt polystyrene too, but won't touch polypropylene.

I had this on a Maytag side-by-side. The bins were marked as made of HIPS - high impact polystyrene. The lugs were part of the bin and hooked into the door.I used this: https://amzn.eu/d/24iPARE
The manufacturers page says it's for HIPS: https://technicqll.pl/en/produkt/rigid-plastic-glu...
HOWEVER: Just sticking the lug back on to the bin was hopeless - the contact area was tiny compared to the size and weight (inc contents) of the bin. So I ended up glueing the entire bin into the fridge. I still wouldn't have trusted it with things like milk bottles. It did work though until we changed the FF 3yrs later.

I hear you.....I'm a bit annoyed as it's only 2.5 years old so resenting stumping up for another one at the moment. I'm sure old fridges lasted forever!I used this: https://amzn.eu/d/24iPARE
