I'd love to see you do a water-floaty test on plastics! Keep uo the good work, guys!

For sure interested in being able to test unmarked plastics!

How silly people assuming that because your material is free and recycled it should be cheap i can make things from reclaimed wood using less tools and people love reclaimed wood items yet your machinery to make items you sell is far more expensive so why should it be cheap you guys make amazing items and you’ve inspired some of my ideas and to start working with plastics

I just bought myself a second hand heated T Shirt press and I'm very excited to start trying to make large sheets with it

PET and PS (Polystyrene) can be done using the injection method, but as you mentioned before, getting the melt temperature right is sometimes hard. The extrusion method is best as the screw moves the plastic at a consistent rate through the heated barrel. NEVER allow the plastic to sit in the barrel for more than 3-5 minutes or it will start to produce toxic fumes. Acrylic can also be used with injection and extrusion molding to make items but is a little more tricky if doing it at home. For those who do not have the ability to buy a machine (vacuum cleaner/shop vac) you can use a 2 liter bottle and a computer fan to make a small vacuum cleaner to pick up the plastic dust. I no longer work in the plastics field as I was forced to retire about 10 years ago due to medical issues, so, though I like your content, I regret that I could never become a patreon or channel member as I barely get enough from the government to support me each month. However, that does not mean I can't help you here by passing on some of the knowledge I gained while working in injection/extrusion molding.

As a Design & Engineering teacher myself, I'm bringing this into my curriculum in a big way starting in a few weeks and will be showing your stuff to the kids.

Whatever they use for the sticker labels I suspect it's something like liquid cement. It's not a drying adhesive but one that stays tacky.

Just a little 'how I do it' regarding the plastic shopping bags, I use a heat gun, but have a cookie pan to contain the plastic bags as I heat them. I wear some leather work gloves to work the plastic and put it in a cake tin (pan] to cool. I also use the heat gun to collapse milk jugs. I get the labels off of the milk jugs first by using a hair drying gun and run it over the label for 10-15 seconds and peel it off. The label adhesive will come off with a little WD40 but then there's the residue from the WD40 to wash off, so there's a trade off. Lastly, for us stubborn Yanks who still use Fahrenheit, that's about 350-370F to get the HDPE into its malleable state. Awesome video with a lot of good questions and bang on answers. P. S. Go with salinity. Saltiness can sound a little 'randy'.

Another way of checking if you have HDPE is by folding it as it shouldn’t have a white line as other plastics do

While it may be more work, I do not have to scrounge for bottle caps etc. I am planning to be forming plastic mallet heads for Croquet. Several of my friends have custom wooden mallets but I was looking for a unique mallet and the HDPE gives me great enthusiasm. Thanks guys. Do you know that there are scale rulers for casting many materials. They are sized to make a mold that when the material is cooled it shrinks to the final size desired. cheers

Hey, does anyone know is the wood from the wooden moulds is somehow treated? Like with a finishing or smt

I wondered about the glue for the labels. But then it is like a latex gum type glue. Strong enough to hold the weight of a label, but no actual holding power. Sadly. I tried about 20 different glues in my garage on bottle lids and nothing stuck. If there was something that would chemically melt and weld the two together that would be awesome. ...or (crazy thinking out loud), is there an epoxy that cures at a really high temperature ? Dunno. I'll stop waffling now :)

I believe the key is surface preparation. You can treat the polyethylene with heptane, which mobilizes the polymer chains at the surface and supposedly allows adhesives to bond to the surface.

The video about sorting plastic using saltwater would be interested. Btw do you have some video about the shredder you are using? I'd be quite interested in that.

theres a piece of kit called a Stuart melting point apparatus that lets you identify semi-known materials with a tiny sample by melting it under a heat lamp while you observe with a built in microscope, its accurate to within 2 degrees or so but that should be sufficient to identify certain polymers.

Yea we could definitely see you 😆

Hey can vinyl from siding be used easily for projects?

Love all your videos. I got interested in recycling plasic years ago after a (different) KZread channel. But really love yours. Anyway, on to.the question. What about PP? My wifes company goes through quite a bit of it that i feel like i should recycle. What are the pros/cons and/or is it worth doing?

Oh wow, somebody asked the best question, what adhesive is holding the labels on, if “nothing” sticks. I wonder if they ever found out the answer.

Pulling taffy

I'm fascinated by all this, but unlikely to do any of it due to space. I am however a collection point for milk bottle tops, although I pass them on and have no idea where they go next. :) I do worry that the use of potable water in any quantity for cleaning, partially reduces the gains, any energy used anywhere in the process has a negative impact on the ecological viability. I'm not knocking what you are doing and I don't have any answers, only questions.

The salinity test sounds interesting

For anyone wondering about the oven thing, in theory yea you can melt in the home/food oven, i don't reccomend, what i reccomend is to get a cheap eletric oven, a new one is not expensive and a used one is dirt cheap, it is what i use it works great if not better then my oven because my oven is quite big

@@BrothersMake I've tried everything for these particular labels. The problem is that they're made of plastic and nothing soaks through it. It's almost like it's thin layers of plastic that's been printed directly onto the bottles. Best method I've found is attempting to scrape it off and it flakes sortof. It's really hard to describe. I have a whole bag full of the labels I've cut around from containers in hopes that someday I can salvage the plastic they're stuck to. Maybe I'll have to send a picture to your Reddit or Instagram to show exactly what I mean. Ps. I've discovered the best way to remove printed on (like ink or paint) labels is to let them soak in hot or boiling water until it becomes room temperature. Dry fully and then you should be able to use your nails to scrape off the paint/ink and it can come off in chunks or flakes. The only thing I've found so far with this type of label are Folgers coffee red plastic tubs.

re: mixing HDPE, LDPE and PP together. This is actually a common industry practice, at least with the LDPE and HDPE mix. They are called plastic alloys. As a example you want something half way between HDPE strength and stiffer than LDPE, manufacturers will blend the two together to get a certain mechanical strength. PP and HDPE can be blend in low percentages. While we in our shop use a lot of shredded HDPE bottle caps, some PP caps do find their way into the mix. Additionally we have experimented with HDPE and PET alloys. There are some companies that make a HDPE/PET alloy for shipping pallets. We have also experimented with the "everything plastic" complete mix of HDPE, LDPE, PET, and whatever plastic films that came in the batch. We have had some luck with it, even the mylar food bags mixed in. We are not the first for that one however. the Andrey Kolev youtube channel is doing a everything plastic with sand mixed in and then extruded to be compression molded to plastic pavers. Mr. Kolev explained that the key for his everything plastic mix was that he pre-extruded the plastic mix, then grind and re extrude to ensure a very thorough mix. His videos were very informative when we started our compression molding experiments. I will warn you that in our personal experiments with the food bags and packaging materials, was something that smelled quite bad when molding (from the food waste residue) but once cooled had minimal odor. We are experimenting with a pelletizing method for these plastics at this time, but not ready quite yet to release publicly.
