Perspex also known as PMMA is almost similar to the definition of plastic in the GateMaterials.db. The molecular structure is (C5-O2-H8)<BR>
<BR>
Plastic: d=1.18 g/cm3 ; n=3; state=solid<BR>
+el: name=Carbon ; n=5<BR>
+el: name=Hydrogen ; n=8<BR>
+el: name=Oxygen ; n=2<BR>
<BR>
In the literature the density is defined as 1.19g/cm3, so you could either use plastic or add a new material. <BR>
