Can polycarbonate be used to store a cryogenic liquid for a short duration, let's say 15-20 minutes.
I've heard that PVC will be really brittle at low temperatures.
What I'm trying to do is a rocket and I need a tank to store my LOX. I need it to be something like PVC or polycarbonate because they are light and cheap enough for my purposes. Also, they are often sold for tubing, the shape I need.
Any other suggestions of material will be greatly appreciated.
