Plexiglas, correctly called acrylic glass, is a plastic with high transparency and translucency, much like glass. The material is very hard and highly resistant to breakage - about 11 times more resistant to breakage than glass.

It consists of polymethyl acrylate and is a so-called thermoplastic, which means it can be deformed under heat. Depending on the design, it is either elastic or impact-reinforced.

Cutting Plexiglas

Due to its strength, acrylic glass can only be cut in very thin material thicknesses. Up to one Thickness of 1 - 2 mm Cutting with the cutter can still work.

It can not cut directly, but only be scratched. After scoring you can break the Plexiglas clean along the scribe edge. In most cases, this results in relatively smooth breaklines (if previously scratched clean).
