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.

It was a very interesting experiment.

👍👍👍. Thank you

gracias,buenisima la practica

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.

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

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

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.

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

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

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

Perfecto!!!!!!!!!!

É um bom teste de Resistencia amigo apredi

great video, very clear, thanks.

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 !

It would be interesting to see bottle tops as they are made of the same hard plastic as bumpers

I don’t understand why the chemical didn’t dissolve the plastic containers the mixtures were put in.

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

Nice video.

Very good

Acetone and thinner is same?

not wearing gloves for this is crazy. I still have superglue on my fingers from last week 😂

شكرا شكرا الف شكر وتحيا أنت رجل محترم جدا جدا جدا ❤❤❤ رجأ اسم السائل من فضلك

Do you spill intentionally it looks that way 😂👌

Once you dissolve it in acetone styrefoam is no longer styrefoam its polystyrene

Quem diria..... Acetona!

ماهو الزجاج الشبكي

اذتكرمت ماهوالسائل الذي تستخدمه لاذابة البلاستك

How about PVC sir?

I tried melting Styrofoam , & plexiglass with acetone in a quart jar. None of it would dissolve like I saw in videos. Even after putting the lid on tight and waiting several days. The acetone bought from Walmart from the paint & solvents section. Supposed to be 100% acetone. WTF?

5:10 oh behave 😁

What liquid are you dissolving the plastic in?

英語わからへんから何も書き込まれへんわ😂

This video is totally BS. The acetone dissolves plastic containers, but not the plastic containers that the mixtures are in? Also, this guy doesn't know the difference between a plastic and an adhesive. The test is a complete joke, and doesn't actually demonstrate anything to do with the "strength" of the plastic.

Que raro que disuelva todos esos elementos, pero la triste copita desechable en la que los coloca, esa no se funde ni se deshace ni le pasa nada, que berraquera, pónganse a hacer algo productivo y no se lucren inventando estupideces, yo no se como les permiten hacer eso.

no logro entender por que el plastico de los vasos de postre se derrite y el del recipiente que los contiene no....alguien que me esplique?
