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

[@TheStigma]

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.

[@a3b4c56]

So if the styrofoam dissolves but cracks on outside of a 5 Gallon Jug, what would you recommend? Xylene & ABS Plastic or is there another plastic substitute that might work? Maybe some powder you can let dry in the bottom. Might try with acetone & styrofoam inside to cover complete bottom as it does not crack all the time.

[@TheStigma]

@@a3b4c56 Sorry, I'm not sure if I understand the question. You are trying to modify a 5 gallon jug? First you should identify the plastic of the jug. It is probably HDPE (recycle code 2), but PP (recycle code 5) is also possible. These plastics are much more flexible (especially HDPE) than polystyrene, so that is probably why you see cracking. HDPE and PP are also notoriously difficult to make any glue or paint stick on (and the same issue will apply to dissolved plastics). You can flame-treat to solve that problem, but that's a whole different topic. The strongest solution for these plastics (if it is applicable for your situation) is plastic-welding. Especially if you are attaching HDPE to HDPE for example. Then it can be as strong as the plastic itself if you do it right. Reinforcements such as wire mesh can also be buried into the repair area to create extra strength if needed. Maybe if you tell me more specifically what you are trying to do then I can help more :)

[@Rabbit.760]

Styrene monomer is their best bet, its more of an oil base than a solvent. DCM, THF, DMF, NMP and DMSO are the best solvents for plastics and they will quickly soften the substrate for a Chemical bond which is the key here. If using acetone, they must sand the substrate with coarse grit for a mechanical bond but i wouldnt expect a watertight seal. Which is why the wood test held up so well in terms of strength

[@TheStigma]

@@Rabbit.760 Does styrene dissolve any of these? I only know it as a thinner for polyester resin. I would like to know more about that. These other solvents you mention I think are difficult or at least expensive to find for a DIYer - but if you know good sources short of a lab supplier that would be useful to know. Probably depends a lot on where you live though.

[@Rabbit.760]

@@TheStigma yes styrene and isoprene are also viscosity and shear rate modifiers in polymer injection molding

[@peregrinefcl5050]

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

[@TheStigma]

ABS (in many car parts and small appliances), PMMA (Acrylic, such as plexiglass) and Polycarbonate (a more premium and much stronger alternative to plexiglass often used in safety glasses, bulletproof glass or transparent plastic roofs/windows where extra strength is required). All of these will dissolve cleanly in Acetone. Polystyrene (for example styrofoam) show in this video only partially dissolves into thick "slime". Useful as a DIY glue, but another solvent like xylene, toluene ect. (often in paint thinners) would be needed to make it fully liquid. Many other plastics soften and swell in acetone, but will never dissolve. The reason the container is not damaged is because it is make of Polypropylene (PP). Almost all plastic containers are made of this plastic that coincidentally is almost immune to solvents and most other chemicals. You should find a recycle triangle with the number 5 on the bottom in most cases. High Density Polyethylene (HDPE) is the other common container plastic you will see, but mainly found in bottles and jugs for chemicals or cleaners. It has recycle code 2 and is also super resistant to chemicals like PP. Do not confuse with the most common bottle plastic Polyethylene terephthalate (PET) with recycle code 1 - used for all soda bottles. PET is much more vulnerable to strong chemicals (like acetone) and can fail and leak quickly. Must check spesific compatibility if considering using PET.

[@stephenmccready9555]

Can glass jars or metal containers be used to to liquefy the plastic in?

[@TheStigma]

@@stephenmccready9555 Yes. Glass or metal containers are the most ideal for acetone (and most other organic solvents) because they do not react at all.

[@werpu12]

ABS and ASA, a non meltable container for instance would be PET/PETG

[@johnnyx53]

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.

[@davidjames1063]

Oooops ! Now you see the SCAM exposed !

[@yewsengcheong1637]

They are polyethylene containers that are resistant to acetone. Different plastics have different properties. The experiment also doesn’t do a good job in that some of the plastics don’t even reach the bottom of the steel bolt. It’s not a scam just trying to say something albeit not every well.

[@wojciechproc]

You've changed my point of view of fixes ❤

[@GausDIY]

Thank You!

[@blynn6240]

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.

I have seen a number if these demonstrations but there is not a ratio of materials provided. Failure could be due to the ratio of acetone to plastic and for the sake of observation, there should be a consistent method that can be repeated so any improvement or failure can be repeated or changed.

[@patten1955]

I had a hole about the size of a dime on the bottom of a hard plastic sewing machine case and used the styrofoam/acetone method on it last night. Don't laugh, but the only styrofoam I could find was an empty sewing thread spool! It dissolved really well and made a nice putty. It's looking really good, but I am wondering how long does it take to dry/cure? It is still a little soft in the middle. I brought it from the garage (cold) into the house hoping that might help. I will need to fill in the other side once it is set up, then sand and paint. Just wondering how long does it take to dry! It's been about 10 hours so far.

You are not testing the strength of the materials, you are testing how they adhere, and even that test is performed badly, as it depends on how diluted those materials are in acetone and how they are spread on the flat support (for instance plexiglass is really badly spread and of cpurse its adhesion is the worst of all). Much more could be said, but i stop here.

Ottime istruzioni, ma posso dire che bisognerebbe stare attenti a postare dei video dove sarebbe meglio usare precauzioni e strumenti adatti, specie se questi video sono pubblici e chiunque li può visionare e imitare, specie ragazzini e adolscenti in cerca di esperienze. Esempio: per spalmare la plastica sciolta sui pezzi di legno le mani dovrebbero essere protette con guanti adatti. Oppure al posto di un taglierino per spalmare, che oltretutto si rovina con la plastica una volta indurita, si potrebbe usare ad esempio una spatola di metallo o di legno.
