Some examples

The polyester glass Poliglass GP3 is commonly used to make plates, rods, profiles, lids and boxes with considerable electrical insulation characteristics at a cost much content. Workable with machine tools, is in some cases painted after processing, to create a further insulating layer which also acts as a protection for the artifact.
