Are we confusing Hard[ened] Rubber with Bakelite, which is a phenol-formaldehyde thermoset resin ? Bak has very good electrical [resistance/breakdown properties, so, as an early synthetic, its main use was in electrical equipment. The two have some similarities in appearance, with Bak being very brittle, as Hans points out, thereby not as good a thermoset "plastic" for wwinds. I cant recall ever seeing a Bak cl ! Don
Thanx, Mark, Don
