- nate_meurer 3y agoThat's like saying "metal is strong". There are huge differences among different plastics.
- ClumsyPilot 3y agoWell, there are < 100 metals but thousands of varieties of plastic?
- nate_meurer 3y agoNot thousands, certainly not in common use. But yes there are many, and they have very different properties from one another, including permeability.
- Gibbon1 3y agoThere is a test for plastics where they weigh a block of plastic then soak it in water and weigh it again. For some plastics the gain in weight can be a few percent.
