Polycarbonate? Is this the right plastic to use?
(OP)
I'm looking for a plastic that have these characteristics:
1)Optically clear
2)Chemically resistant (particularly against oil, petroleum based chemicals)
3)Impact resistant / durable
4) Easy to mold
Any recommendations would be helpful. Thank you.

No,PC is not chemical attack rsistant,especially petrol.
The polymer that have all your required characters is: transparent PA12,whose features are as below:
* Clear transparency even in high wall thicknesses
* Good light natural colour
* Can be coloured in transparent as well as opaque colours
* high toughness at low temperature
* high fatigue strength
* Excellent chemical(i.e petrol oil)and stress-crack resistance
* High resistance to cooking water
* Ductile breakage, high flexibility
Hope this will help you

If need to withstand higer than 100 centigrade,PA12 is preferable,it's HDT reach 135 or so.
It's up to your working condition.
Since the material should be optically clear, no filler can be added in order to improve the HDT.

Cellulose propionate is reasonably clear.Better than PVC and almost as good as PC.
He still has not replied re student status, so maybe he is cheating on his homework?
135 deg C is very high for unfilled nylon 12 unless you are confusing it with something like Reny or some grades of Grilamid more often described as nylon MDX or aromatic nylons.

I'm actually an Industrial Designer; having worked primarily in consumer electronics. I'm working on a helmet and needed insight on plastics. I'm unfamiliar outside of plastics like ABS for CE...
I don't think heat will be an issue, but voltage may be. As some safety helmets have a class rating for how much shock it can absorb.
Thanks again guys.
RE: Polycarbonate? Is this the right plastic to use?
Probably PP random co-polymer will do. They have some pretty good transparency now and are used for clear containers in under bonnet (hood) applications.

Much tougher than acrylic and much more solvent stress crack resistent than PC and about as clear as PC.

Why be happy when you can be normal?

The Japanese make one called Reny that is pretty similar I think.
I'm not sure who does the old Trogamid now, maybe that is EMS also
Transparent nylons where a lot more expensive than propionate although that may have changed as cellulosics have escalated a quite a bit due to increased environmental control costs.
