I’ve done number 5 plastic outdoors in a toaster oven. It is way stickier than number 2 plastic melted but if you can get it in a mold and press it with a clamp or vice until it sets number 5 plastic makes better material to shape into parts.

I must admit, this is more fun than watching latex paint dry out.

I bit the bullet and bought a new toaster oven that is 1000 watts. I hook it up to my 1500 watt inverter and battery bank that are charged by my solar panels. I have only melted HDPE so far. Looking to experiment with other types. Thanks for your videos. Peace.

PP Aka #5 is also commonly available as those orange translucent prescription bottles from places like Walgreens, hope to use some for a Wand handle prop.

coming soon. I'm doing these things in steps to be able to refer back. This part was to show time and temperature details and how soft and flow rate in an open melt. as time goes by I will do videos on press forming, injection molding, and other possible forming methods all referring back to this which is the foundation information for Polypropylene in this series. Unfortunately in the mean time I had a case of bacterial or viral infection that was treated with an antibiotic which caused a reaction with some pretty negative results I'm recovering from. I'm hoping to get back up and running this month, though will be starting out slowly with other materials first.

Heres a block of PP I melted to form the base of a tool I use to break down PET plastic bottles (and likely other plastic bottles) into plastic ribbons: kzread.info/dash/bejne/eYyny6uCZs7Up9o.html which I can then use as lacing, cordage, or to make baskets out of (in the same way I use paper strips here: kzread.info/dash/bejne/ZmGEupmHnb2clbg.html, )

Hello, i have a question. Is there any additives to add if you melt polypropylene to make it durable like making bed tables.

Quite interesting! Could you share how much time,temperature and power required, please?

thanks for sharing~ so what can we do with the melted plastic? Any ideas for decoration? or how to reuse, shape or mold them? thanks!!

+Molly Liu that's the idea. I'll go back and make a variety of thing using these materials for future projects. These were just a basic intro set on the six types of plastic and their melting and forming characteristics. If you sculpted something in clay and made plaster molds from it you could press form all sorts of things with this. the biggest trick with this is that PP is annoyingly resistant to gluing so you may want to leave raised bit on the back to drill a hole and put a lace through or stitch it to something. You could make buttons, charms, knobs for drawers and cabinets, beads, game pieces, coasters and if you form them into blocks you can make pretty much anything you would make out of wood.

@@RovingJack , outside with the breeze coming from behind, plastic welding works great. A soldering iron or any hot enough steel rod works. Hot coals in a small hole in the ground should heat a rod enough. If not, make a bellows using wood, vynal and tacks. Just get the two parts melted together and grow in skill as go. Tack the two parts together at both ends and maybe a few places between, before begining the bead. I just made some long beads and welded a wheelbarrow given to me. It's strong enough and water tight. Adding filler plastic to the bead is best.

Can you machine it in a lathe?

excellent .functions and spasifction.shoud be explained

So it does not warp like hdpe when it cools?

If (PP) was melted, can it be used as a glue to patch a 1cm hole (bottom of a flower pot) if the flower pot was also made from (PP) plastic? if so would the seal break, would it be weak or leak water? thanks

@RovingJack

it's a bit more like welding, but yes you could do it. it's kind of tricky to get right you'll want to melt the edges of the hole and the edges of the patch/plug at the same time and then clamp them together to cool. It shouldn't leak unless there are small pinhole gaps and shouldn't be weak, but the area around then that cracked to make the hole may crack again/more over time. And the weld is likely to be a little ugly, but if you scrape or sand it to make it look better you may weaken it. I really depends on the pieces, age, how melted, matched and they way you clamp and press the pieces together.

Very inspiring. Does it lower it's mechanical values? I mean, can you create elastic junction like on 1:30?

I don't usually try to make a new living hinge again with remelts. all plastics degrade very slightly each time the are reprocessed. getting a bit more brittle. Not enough that you will usually notice after one melt, but over time they suffer just like plastics left outside in the elements for years suffer.

@RovingJack

there are also some plastics that will work better with 'quenching'. PET in particular if left to cool becomes opaque, brittle and hard, but if dropped in cold water remains transluscent, flexible and plastic/elastic as the bottles they come from.

it's well below burning or boiling temperatures for the compounds in PP. On top of that PP is a compound that is considere safe for internal body use in medical applications (so leaching plasticisers are not found to be and issue for the bodies health in exposures like that the fraction of those that are present in vapor point releases during reforming are not a health concern). Generally speaking it's always best to do and chemical experiments in a place with decent ventilation anyway, but unless you are doing it in metric tons of PP each day for years your more likely to face health complications from the city water supply in whatever place you live in the world.

Hello I have a question. I want to melt (in a drippy way and not carbononized) the middle of a chair that is made out of propylene reinforced with glass fiber. Would I be able to do that and how? The chair is expensive and I don’t have a do over chance. Thank you in advance for the help! X

@RovingJack

the glass fiber will likely prevent the Polypropylene from moving in 'a drippy' way. the reinforcement will prevent gross deformation even if you got the plastic to a liquid state. think of it like denim coated in candle wax, you may liquify the wax with the right temperature and the cloth might sag, but it will never completely melt holes and form drips.

@RovingJack

I'd say your best method would be to replicate the part to be melted in a non reinforced meltable material and deform the replicated part.

I use a dedicated toaster oven I got at a thrift store for crafting and not food. in my younger days I used the household oven for polymer clay, shrink plastic crafts, and fused bead sun catchers, and those are more likely to produce fumes and smells, but doing things once or twice is not a huge deal if you can heat it, clean it and not cook in it directly after. But doing this sort of thing often enough, it just makes sense to have a toaster oven specifically for this.

Thanks for the reply. I thought about getting one second hand. Thrift shops don't always have one. New toaster ovens can be had at the low end for less than to mid $20's now.

We have polyethylene and polypropylene... how about polybutylene (some pipes are made of this)?

@RovingJack

7 жыл бұрын

I don't have much experience with it, I'll look and see if I can find some, though scavenged and salvaged is likely to come from water pipes which they are no longer approved for here due to chlorinated water chemically causing deterioration and breakdown resulting in plumbing failures. As a reasonably stable thermoplastic it might be useful, but availability is likely to be a limiting factor towards it's usefulness.

Caution if you're overheat the plastic polypropylene it will make chemicals and it will turn into a liquid lava and it can't be moltened

I generally don't need to mix them and am not sure why you would want to. It's possible to mix the PE (high and low density) and PP. I'm not sure if molecularly they blend or if it's more like a cogealed suspension. ldpe and pp have such relatively close properties that they'd be the easiest to work together. Again I'm not sure why though. HDPE is a bit more tempermental and if you were looking to find a way to soften it for working I'd say LDPE is a better option due to similarities in chemical compositing. Both PP and HDPE are relatively abundant. what's the application you intend?

One big problem with mixing plastics, is the fact that you can't un-mix them. This keeps you from ever being able to recycle the resultant object.

Can anyone see to read the text on the screen?

Seems there must be something the polypropylene doesn't stick to. For most building projects it will be necessary.

How to expend effort converting plastic originally in useful shapes into garbage. It would be more productive to cast the melt into blocks, sheets, etc.. of consistent dimensions which can be machined into something useful. And that music is horrific.

Thanks for your comment, this is only an introduction to sourcing, equiptment used, time and temperatures used in working a given material. It's intended to inform for starting ones own experiments, and for back reference in future video of making components and tools from scrap plastics so that I don't have to explain or demonstrate this each time I make something from polypropylene, Like I did most recently for making a tool for turning PET bottles into cordage, in which the tool is made out of a block of PP made from lids from food containers. I can simply show the tool being made and link back here for how I made the block I started with.

these are meant as back reference videos for referring to later when creating thinks with the materials. I'm currently not able to get to my workshop right now as I travel the country talking with hundreds of makers and the makerspaces the work in about their projects and processes, but there will be videos in the future (actually I did one already with PP lids into a tool for breaking down PET bottles into ribbon but...) shaping components of projects. But in the end this is a series of videos by a hobbyist recycler and tinkerer. there are people who have done complete materials analysis and properties studies of this sort of thing, that is not my goal.
