[Amps] Corian for HV insulators?

[Jim Barber]

Those are made from extruded HDPE. (High Density Polyethylene)

. It's almost indestructible indoors, but deteriorates with exposure to UV

. It does not cut or machine well. The more expensive cast HDPE type is 
better in this regard, but more expensive. :-) You can tell the 
difference by the texture. Extruded has a slick, almost "greasy" feel 
and is rubbery to bend and flex. Cast has a harder finish and doesn't 
bend as easily.
