Looks like 5K Series and EE series.
No data sheets found but probably solid poly and I wouldn't worry about them.

Yup. Definately Apaq. They are polys, but only time will tell whether they are good polys.

Fujitsu and Elite poly's are known for exploding under heavy conditions (overclocking on PSU's with bad caps). Trodas collected some examples here and on other sites too.

kc8adu has also seen a few bad polys on boards.

The early Fujitsu Hybrid Polymers did have occasional problems but those aren't solid polymer.
They were wet and their problem was moisture leaking IN.

As to your thread try reading it.
The only bad polys there were blown by a bad PSU. It says so.

What do you expect. - He works on industrial equipment.
Factory/machine shop conditions can blow any cap especially when morons block vents let chips and other crap into the mobo bay.

I haven't seen a 'bad brand' of poly caps. - None.

Lytics fail because they are full of liquid that undergoes chemical reactions usually by reacting with impurities in the aluminum.

Solid Polymers got no liquid.
Same failure modes -> can't happen.
