Top 5 Easy Ways to Make Liquid Plastic and Compare Their Strengths

3 types of plastic here: polystyrene (styrofoam, cdcase, yoghurtcup), abs (bumper), and acryllic (plexiglass). The polystyrene is just in different forms, but you should get the same result if properly dissolved. Acetone does not properly dissolve polystyrene, so this won't work too well. Need a different solvent like xylene. ABS and acryllic does dissolve in acetone though. In general acetone is a problematic solvent because it evaporates too fast and leaves lots of bubbles. This porosity is the main reason for why the tests are so brittle. It is difficult to avoid even with a better solvent anytime you try to make a thick piece instead of of layering many films (tedious). A solvent-evaporation plastic is just not good for this job of making thick castings. It is the reason why commerical products (like epoxy) are all based on thermoset curing plastics and not solvents. This is still useful for thin films surface treatments and repairing small cracks though. You can also make DIY "fiberglass" type things.

Really appreciate. What types of plastic can be used for mixing acetone? Meanwhile, the container for acetone is made of plastic but does not melt

gracias,buenisima la practica

Interesante. Buen trabajo. Me parece que el segundo método para medir la resistencia es el más adecuado.

This was very interesting! I had a hunch that it would be the bumper, which I think is called ABS plastic. It’s the same plastic used in everything from bumpers to safety helmets to the inside of your refrigerator. It has a bit of give but it’s very tough. Styrene (CD case) can be made crystal clear but is very brittle. Yogurt cup (polypropylene) is flexible and approved for food storage , and will not shatter like styrene. Nylon would probably do well with your test but you’d either need to use heat or some other industrial solvent to melt it.

It was a very interesting experiment.

Wuuuuuuuaaaaasoooooo pero qué interesante hay varios plásticos que se pueden derretir y la verdad que no sabía. Muchas gracias por este video instructivo

I've made a few of these glues. what I've learned so far is that their consistency before applying is a huge factor in strength. my favorite is the plexiglass & ABS variants for welding and patching.

Perfecto!!!!!!!!!!

Buenas . excelente .q recomendación de los pegantes anteriores para reparar plástico de motos y autos . gracias

Great channel . Mate, does the ABS plastic disolves in aceton?

👍👍👍. Thank you

É um bom teste de Resistencia amigo apredi

JOB WELL DONE AND VERY NEEDED KEEP IT UP MY FRIEND!!!

great video, very clear, thanks.

I really appreciate the test and the time you took- but it seems more like you’re testing the strength of adherence of the plastic to the metal bolt, whatever that clear sheet of plastic you were using at the base for the first test or the wood. Not the strength of the actual plastic... But granted, that would be much harder to test…maybe if you made the samples into a thick column, then put your loop device around it and applied pressure?. But still, the results can be useful if you’re needing a plastic to adhere to one of these surfaces Also, the samples weren’t really stirred and some appeared to not be complete dissolved. I have no idea if that would affect the results… But I would imagine an uneven ratio of acetone to plastic would make a difference. Now maybe you were trying to limit your contact with the chemicals (understandable). I also don’t know if you used the same amount of acetone for the same weight of plastic… although granted that would be tricky to do with all the different plastics if they have different densities.

Gracias por tomarte el tiempo de hacer estas pruebas, m fueron de mucha ayuda, saludos desde mexicali mx

It was very valuable information. Keep it up, your friend from Iraq

Pode me ajudar ? 1- a acetona pode ser substituida por outro produto ? 2- o plástico para choque (bumper) é igual , ou similar ao ABS ? Obrigado, parabéns pelo vídeo, muito bom !

Very good
