Suitable plastics for cryogenic service
(OP)
Does anybody have suggestions on what kind of plastic to use in a cyrogenic vessel. The liquid is approx. -300° F.
The plastic would only be exposed periodically, maybe twice a day for about 1 to 2 minutes at a time. I've thought of using PFA but wanted to find alternatives.
No stresses are applied to the piece except for thermal shock.

It's very important to understand the impact loading, and other characteristics of the plastic and how the plastic you plan on using will handle them. So all uses of Vespel in cryogenic service may not be bad for example, but there are plenty of other materials I've found which are suitable and better for the vast majority of services I've had.
