Acrylic is easily scratchable. Is the above quote just an assumption of the author or something which the researchers claim?

- kps 5y agoAcrylic is a little easier to scratch than plain glass, but not much. (Polycarbonate, which might be mistaken for acrylic out in the world, is very easy to scratch.)
- detritus 5y agoI work with acrylic every day and I'm telling you - it scratches a helluva lot easier than plain glass. You can practically just show it something with a higher shore rating and it'll scratch itself... .
- silisili 5y agoIn terms of Mohs hardness, acrylic is around 3 and glass closer to 6. This means, in theory, things like a coin or razor knife could scratch acrylic, but not glass. How this hybrid behaves though, I'd have no idea.
- qwertox 5y agoOh, you're right, I thought Makrolon -- which I was using as a desk surface protector -- was acrylic but it turns out to be polycarbonate.
- rini17 5y agoIt is acrylic-glass composite, so it should be more scratch resistant than pure acrylic. And it's glass flakes so they can use hardest glass available. However scratches are only aesthetic defect and can be prevented by foldable phone case. Cracked screens are much bigger practical issue.
