Types of plastic
An overview of the different types of plastic, these are the most common ones. We mostly work with PP, HDPE, LDPE and PS. Just because we gather that the most from our waste here. However they should al work with our machines, just requires some (temperature) testing.
Does anyone have experience with shredding ABS from printers/copiers? jtravis recycled some of those ABS cases with a wood chipper but I wonder how well that goes with the precious plastic shredder. I have piles of it at my school but these things are quite hard. I suppose much depends on the power of the engine..
yes for sure you can!i have tried that with the injection and was fine!
I am interested in to recycle ABS, it is possible wiht the precious plastic machines?
I am building the machines to recycle polycarbonate lenses into square molds to use as floor tiles. Are there any potential dangers when grinding/melting polycarbonate? Harmful gases? Thanks!
I’m working in a project to recycle a multilayer bags used to food packaging and more..
The problem is that when I try to melt it, it doesn’t work properly because some part melt good and other just burned.. Do you have any ideas how to fix this?
There are different types of plastics comes in market. These plastics are actually used in creating 3D filaments. A different plastic is used to create the different type of filament-like ABS, PLA or PET.
What about recycling plastic bags and film? Can these be recycled with this process??
Can anyone tell me that what steel wire to use for the line tie / bait harness. From what I’ve been able to find, .024 to .028 is the popular size, and torsion straightened steel is preferred, is that correct?
Thanks in advance!
Yeah i feared for that… Lasercutting PVC is also a bad idea… There doesn’t seem to be any easy way to recycle that shit
Thermoplasts can be recycled (by heat the material gets softened) (bins, bottles, bags, bottle caps, plastic cuttelry etc.)
Thermosets can not be recycled the Precious Plastic way (by heat it degrades and burns) (epoxy, urethane polyester etc.)
However most toys and kitchenware are thermoplastic so possible to recycle.
If you want to know anything about HDPE here’s an extremely comprehensive page including history, application, recycling, research etc. https://provprocure.com/hdpe-high-density-polyethylene/
Does the plastic strength decreases after melting or are there other material which are mixed with the plastic to maintain its strength.
Hi guys, just wanted to know if PP, PE and/or PS were suitable for 3D printers
So im new to plastic but i have a question. How are some companies making blocks or construction materials with out separating the plastic?
Thanks for the fast response, perhaps HDPE is the best material for my application! I’m making a wood frame backpack, however, the wood-to-wood glue joints seem to be the weak point. I thought that replacing the wood cross-members with a relatively stiff polymer (with an elastic range) might be the best option to prevent fractures from stress or big drops.
Any ideas on the best ways to learn about and get hands on experience with the PE’s?
Thanks for sharing these graphics! Curious if you have worked with or know any resources you could suggest for learning about turning a recycled plastic into a dense foam? I’d love to make or source a recycled plastic that is stiff but elastic enough to take some rough handling without fracturing.
Thanks for any help!
I would also like to know as i will be doing a DIY project. Currently I have empty HDPE bottles and mostly (detergent bottles or oil bottles). Thank you!
Hi, did anyone has an experience with HDPE? I would like to know about mechanical properties of recycled HDPE in comparison with virgin HDPE. Thanks.
thanks that info help me a lot in plastic classification. Dave, thanks for your help. Earth proud of you.
What do you know about ?
I heard the oxo degradable plastic is not good.
Im working on helping restaurants go to alternatives.
Thanks! great Job! i thin. this tables should be added to V3.0 docs!
@premuth ¿haz encontrado un buen reuso para el PET?
Unfortunately, spammers took over the site and I just didn’t have the time needed to manage it all. 🙁
