How to Identify Any Type of Plastic | Orange Plastics Academy

Need to find out what type of plastic a specific product or part is made from? In this injection molding video, you’ll discover how to identify a type of plastic with:
1. the sink-or-float test
2. a compression test, or
3. by burning it

Would have been better if you actually demonstrated the tests rather than skip half of the tests while explaining them. Most people probably won't know for sure what you mean by "oil like substance" VS "grease like effect". If you could actually show these tests being done in full, it would be much more useful.

[@minnie383]

Thank you. Have you thought if doing a quiz-type video, where you show how a bit of plastic behaves in these tests and we could guess what it is?

[@justinpark9089]

it is simple and helpful guide. i really like this video!!

[@HRIservicesllcSturgeonBay]

Thank you, great video!

[@veervikramsingh8649]

It's useful information. Thanks for updating.

[@bkkunalsharma233]

very useful & important topic about plastic

[@sharrayahchelseanavarro8819]

what compressor did you use?

[@charlaparedes2297]

How do I separate PET from other plastics by sink and float and what solution should I use?

[@01mustang05]

I want help to identify plastic types in things like assortments of unlabeled plastic shopping bags and various product bags; plastic types in kids car seats and other things for kids; bottle tops, seals, and the rings; used up gift cards and expired credit cards and alike; cell phone cases; and plastics metal scrappers separate. I also want to know what's not being recycled and why. Or are we switching from petroleum plastics to something more safer and non-toxic?

[@adnanahmad6084]

Without these three test perform. I can identify any type of plastics. By hands or eyes visually and chewing by teeth. I have diploma engineering in plastic technology from Aligarh Muslim university UP India.

How can you do this? I think that smell the fire is dangerous for us

[@mallikarjunbhatmurgi2829]

Thanks to ORANGE PLASTIC

[@mallikarjunbhatmurgi2829]

Very good information

[@7smr]

I just thought of an idea. Since most plastics these days are identified by letters or a logo for recycling, you can conduct your own experiments by burning them and identify the color and smells from them. You can then try the same with an unknown plastic to see if it matches the same characteristics.

[@akinordman7145]

Well shit. You burned my idea.

[@01mustang05]

[@kubersinghtomar7152]

Good morning, very informative video. Thanks a lot for make like this videos. Can you please make a video on BOPP, PE, PP AND PET

[@Mriya6]

How would you seperate HDPE from LDPE if they both float?

[@MGoudsmits]

can you repair a tine crack in a POM tube?

[@diveshsharma2373]

Nice Keep it up

[@mariama.mohamed3695]

Very good

[@jannikheidemann3805]

Can you make the same video, but about bioplastics and how to identify them? Edit: To be more precise: Of course the process for identifying chemically identical plastics made from non-fossil raw materials is the same as for thier fossil based counterparts. I was thinking of degradable plastics and those non-degradable plastics that can be made conveniently and efficiently from the types of fresh biomass that is widely available.

[@Archentides]

How do you determine Polyphenylene Ether or Polyphenylene Oxide?

[@omkarmagar4246]

Helpful

[@user-lh5ze3bk6z]

How can I will test TPO and PVB?

[@talalibo8252]

Pls Can u tell me sensors that can classify these types of plastic automatic. Pls not NIR spectroscopy or similar one.

[@joydhua8501]

Which plastics are dispossable

[@danreynolds8028]

Would like to know the best glue to repair cracked or broken plastics, especially PP and PE. Many types of glue will just not bond to these 2.

[@arbiter-pe3xg]

any sort of cyanoacrylate glue should work as it sorta acts like an acid for the first few seconds and fuses the two parts together before hardening

[@ReadyUpGo]

After years of failure testing many varieties of glues, I heard about plastic welding, which I use over bonding agents whenever possible. Using soldering irons for melting plastics, even with adjustable temperature control, proved difficult and largely unsuccessful. I find that my heat guns work very well but required making custom tips to limit and deliver the hot air precisely. (Beware of overheating the inside of the gun when restricting the air flow). In my uneducated brief experience with this, I believe it essential to use the same kind of plastic as the part to be repaired when welding. (note: my Smoothy wax melting/shaping hot air butane torch has proven to be too hot to be of use unless a long tubular tip is made to allow cooling before application of air on plastics.) My respect and gratitude to Orange Plastics.

[@mizzprezli]

5 second fix, it works best on clear plastics but I've used it on solid color plastics with success

[@ABDULREHMAN-by7zk]

Toulene

[@siddheshpatil8491]

Good 👍🏻

[@PanamaSticks]

Having used the procedures several times to identify plastics, I have to say there are big problems. Excepting the float test, they are destructive! What if you're trying to identify a plastic to repair an irreplaceable device?

[@JC-ms2rz]

PVC?

[@ThatcarguyonPS5]

you guys make me take a test

[@Erhannis]

How about PTFE?

[@annie-ne3gy]

Hello! Can I ask which sensor should I use if I want to detect different types of plastic (PET, PVC etc)? They have different wavelengths but I'm not sure which sensor to use for detecting them separately. Also, from where can I get it? Or how to make one?

[@sageminentjunky5197]

Amazon

[@akashkumarn6580]

Thank you

[@mrRizwanFantastic]

sir,should you discuss by its common structure that we are usually used in our daily life.it can better understandable.. thank you

[@01mustang05]

Yes; I want help to identify plastic types in things like assortments of unlabeled plastic shopping bags and various product bags; plastic types in kids car seats and other things for kids; bottle tops, seals, and the rings; used up gift cards and expired credit cards and alike; cell phone cases; and plastics metal scrappers separate. I also want to know what's not being recycled and why. Or are we switching from petroleum plastics to something more safer and non-toxic?

[@toddster8793]

I have a question for your expertise: I'd like to fabricate sliding plates for goalie my pads (for inline hockey). Which plastic would be light, durable and slide the best on an inline hockey rink surface?

[@arbiter-pe3xg]

HDPE would be a good bet as it is light, strong yet flexible and can be found in most milk cartons and drink lids, it can be identified easily by its recycling symbol with the number 2

[@whateverrandomnumber]

But will it blend?

[@sageminentjunky5197]

Most likely no unless the plastic have near similar properties

[@iqbala1104]

How to see the difference between HDPE and LDPE ?

[@jiarongli2799]

MFI and particle appearance are different.

[@javidsekh6850]

Tell me please whot is abs plastic 😭

[@sideswipe147]

Not really what I needed. Need to know how to tell if a plastic is halogenated or not.

[@TEKKKNO]

Im here looking for HDPE and i see there's no hdpe in types list

[@dylanfoley5693]

What info about HDPE are you looking for?

[@alhassanali3305]

Super goop go on I waiting more videos

[@mimiescape2023]

Assuming you have extra plastic to burn and not actually trying to repair the pieces you do have....

[@DellAnderson]

What the h#$2 is "oil like substance" or "candlelike grease effect". Is PE and PP so expensive you couldn't find any to demo? That's all I came here for: Distinguish HDPE vs PP. Still not sure what I have.

[@reddragongaming8501]

Hell is not a curse word you know

[@DellAnderson]

@@reddragongaming8501 Who said anything about that word? And why would you think they did? There are multiple 4 letter words starting with "h" I can think of. Now back to the topic -- what is "candlelight grease effect" or "oil like substance". Found another video with some actual samples of HDPE and PP. I had PP, which welds similarly at similar temp to HDPE apparently, smells waxy when heated, but requires PP not PE to weld. Quite a learning experience.

[@mathiamutua6680]

Name different plastics shown in the video and find their melting points

[@rob379lqz]

My little 2-person fishing boat is made of ABS. It floats????? 😳

[@hotcoffee1068]

Tanker vessel made from steel also float 😂

[@THCMusicBlog]

heh PP floats
