At my work, there are scraps of clear plastic sheet that was once used as a machine guard at my workplace. It’s flexible and tough and is about 7.25mm (or .28 inches) thick. I’d guess it’s vinyl but I can find its like nowhere on the internet. I want an 18 inch square of it for a project at home but none of the scraps at work are big enough and I can find nowhere to order more.

[You can see a photo I took of one of the scraps here.](https://mltshp.com/p/1NVYO)

Can anyone identify this material and help me find where I can get more of it?

Sounds like Lexan.

I think it’s vinyl, and the easiest way of finding it in that thickness in a reasonable size is to get a 1’ tube and cut it apart:

Looks like what i’d call Perspex.

I’m going to suggest either vinyl or PVC. It looks _exactly_ like walk-in cooler/freezer strip curtains, except a lot thicker.

Depending on what you’re doing with it, a section of a strip curtain might work for you.

Something like this, just thicker.

I don’t think it’s polycarbonate (lexan) or acrylic (perspex), I can bend a 6 inch square of this material fully in half with my bare hands then flatten it out again. Those materials are workable but not THAT workable, and certainly not by hand.

I’ve looked into vinyl tubing, but to get an 18 inch square out of tubing I’d need a 6 inch diameter tube, which seems like larger than you typically see flexible vinyl tube offered.

I have a friend who works at the aforementioned McMaster-Carr. Their customer service team lives for answering questions like this, and finding & delivering the product. I highly recommend just giving them a call and seeing if they can scrounge up the exact product you need.

You can order a piece of 20 mil vinyl sheet from [Amazon to try out](https://www.amazon.com/VViViD-Multi-Purpose-Heavy-Duty-Tablecloth-Protective/dp/B0758X7Y1D/ref=sr_1_4?crid=G34NRSHKQ6OS&keywords=vinyl+sheet&qid=1662062562&sprefix=vinyl+sheet%2Caps%2C88&sr=8-4). Pretty good price at $14 bucks for over 6 sq. ft.

The HQ is only 20 mins from where I live. I’m surprised I don’t have MORE friends that work there! Actually I had another friend who worked there for years but she passed away. As far as I know all of their customer service reps are people with un-used masters degrees. So far that is true for 2/2 people I know who have done customer service there.

Yes - the material in your photo is MUCH more flexible than Lexan or Perspex (aka Plexiglas / Lucite / poly methyl methacrylate).

If McMaster-Carr comes up empty-handed, try Grainger next. If they both come up dry you’re down to duct tape, bailing wire, and spit to git 'er done! 😉

You can also get clear Polyeurethane sheets , maybe better for UV and chemical resistance. ? toughness ? strength ?

There is acrylic too but its easily degraded.

Those are clear flexible PVC panels.

Grainger has them in strips and they are not 18 inch wide [https://www.grainger.com/category/material-handling/dock-equipment/strip-doors-replacement-strips-and-hardware/replacement-strips?attrs=Roll%2FStrip|Roll&brandName=TMI&filters=attrs%2CbrandName](https://www.grainger.com/category/material-handling/dock-equipment/strip-doors-replacement-strips-and-hardware/replacement-strips?attrs=Roll%2FStrip%7CRoll&brandName=TMI&filters=attrs%2CbrandName)

Give TMI a call and see if they would give or sell you a small piece. They have this in their catalog on Page 6 - STANDARD CLEAR PVC PANEL (0° to 150° F) with thickness upto 1/2 inch but they come in 60 ft rolls. Call them and they may be able to work something out.

I have no affiliations to TMI

Maybe something like this stuff? Square slabs of clear PVC, so you don’t need to buy a big roll of the stuff. I don’t see one that is the exact thickness of your example.

Phooey. I was looking for thick PVC that would meet or exceed the 18" width and didn’t note the Rockwell hardness rating.

Looking for PVC table covers and floor mats might get you different options than industrial supply websites. Here is a clear flexible table cover. At 3mm, it’s not as thick as you are looking for, but suggests some different ideas for search terms.
