Dust extraction system - PVC versus Acrylic ducting

[Thedog]

Hello,

I am about to add 100mm solid pipe ducting to my Camvac extractor to service a few tools (Table saw, thicknesser and band saw).
It seems that most 100mm solid clear ducting used for this is PVC and not acrylic or polycarbonate.
I am no expert in this but from I thought PVC would cause a lot more static build up compared to acrylic or polycarbonate ducting.

Why is most standard available ducting for woodworking made from PVC? Or is still the best option when added with some earthing straps for static discharge?

Any views or advice would be good.

Cheers

Acrylic has rotten static as I recall.
Polycarb for impact resistance but it's more expensive and soft.
Have you looked at metal ? It's the best functional choice.
