Nothing is non-conductive. Static buildup can result in a nasty shock on plastics because the voltage is high enough to allow current flow across the surface and into your fingers.


Which is why when you use PVC pipe to build a dust collection system you need to ground it. it doesn't do much for small shocks but the larger higher voltage ones are reduced. Many people consider that to be a waste of time, but imagine 25,000 volts sparking in a dusty room.
