We wanted to know. What can our hybrid glass actually withstand? Okay, we already knew that our flexible material is very pliable and therefore shatterproof. We also determined the surface hardness to be up to 9H. Damn hard and resistant to scratches. But how does that look in the extreme test? We had just recently received a customer request that seemed very extreme: Is our hybrid glass capable of protecting touch displays used to control welding equipment in a welding shop from sparks, fire and dirt?

Cut-off grinder vs. hybrid glass

After we had scoured our workshop for a cut-off grinder, the test could almost begin. First of all, we had to find a solid iron block that we could process with our cut-off grinder. After fixing the iron block on wooden pallets stacked on top of each other, we could start. We worked on the piece of iron with the cut-off grinder and generated a decent amount of hot sparks, which we directed directly at the hybrid glass at a distance of about 60 cm. Speaking of hybrid glass: We produced the test object in a size of approx. 40 x 50 cm and mounted it directly on a silver-gray backprinted plexiglas plate without bubbles so that we could see anything at all. Otherwise we would have seen sparks on transparent glass, or not seen because it is transparent! Afterwards, we wanted to know how our hybrid glass material performed and whether it was still stable enough to be mechanically stressed. But how? Scratch tests are a dime a dozen. 9H surface hardness is super hard, we already knew that. Then we came up with a crazy idea: What would happen if we hit the already sparking hybrid glass massively with a hammer?

Hammer versus hybrid glass

So now we had the second test in mind: we wanted to hit the Hybdrid glass material hard with a hammer. We could not imagine that the special material would withstand a hammer blow, since glass typically breaks relatively easily, at least when hit hard with a hammer. The well-known bulletproof glass has already been tested and discussed in various videos and forums. We knew that bulletproof glass breaks. How will our hybrid glass behave? Unlike bulletproof glass, it is very flexible.

Everything documented on video

As a manufacturer, you could of course talk up such a test. But for sure we don't want to do that. For this reason, we recorded all tests on video, both the heat test with the sparks and the hammer test. The results completely surprised us. Despite massive bombardment with hot, still burning sparks, there is not a single hole in the screen protector material! Although there are some minor dim spots, the plexiglass panel underneath did not get any scratches. And, we certainly shot the hybrid glass for a total of 6-8 minutes. Of course, we shortened this to a few minutes in the video (otherwise it would have been quite boring). We didn't expect at all how the hybrid glass would perform in the subsequent hammer blow test - in the truest sense of the word. The heavy hammer blow destroys the plexiglass plate - but the hybrid glass remains tough. We would never have expected that. But check it out for yourself in the following video.
