I am working on a project which involves the use of polycarbonate. Polycarbonate is quite a new material to me as I haven't worked with it yet. I want to know its characteristics in detail, as it would help me in my project. Here they go:

  1. Is polycarbonate strong enough to withstand pressures up to 20 atm? If the surface has a slight curvature, can it retain the curvature under such high pressures?
  2. Is polycarbonate resistant to inhospitable temperatures as low as -200˚C?

  • $\begingroup$ Being "resistant" or "strong enough" is quite not clear. Then again, I doubt PC is right pick for whatever you want to do. $\endgroup$

  • $\begingroup$ "withstand pressures up to 20 atm?" Certainly -- in a thick enough piece. You need to be more specific, and do some research. Polycarbonate cryogenic supplies are sold (e.g., grainger.com/category/lab-supplies/lab-diagnostics/…), so consult the literature and manufacturer for specs. $\endgroup$
