PVC plastic would be the best insulator.
There are various densities of PVC, so this is impossible to answer.
Thank you.
Paper is flexible because you can bend it. That is how I know instead of going on the internet.
So, the full or long form of PVC is 'polyvinyl chloride'.it is the third most used thermoplastic polymer and polythylene and polypropylene! BY- MR. DAKSH KUMAR SINGH!
Depends on what king of PVC and what's the concentration of the acid. For example the 35% HCl damages the flexible PVC on 50°C, but the rigid PVC not... (The flexible PVC become rigid I think.)

The smaller sizes are more flexible. Colder temps affect flexibility.
None. PVC is not made to be glued to concrete.

I have never seen flexible PVC. However It does not seem like a good idea to use flexible piping for the suction side of the system especial y with the weight of fill on top of it. even on the pressure side there could be problems with the possibility that the weight of the fill on top of the tubing would eventualy flatten it.
PVC in its native state is fairly rigid. Flexible PVC ("Vinyl") is made by adding plasticizers to the material. In the old days, compounds such as octyl phthalate were simply added into the mix and would slowly leach out or evaporate over time; this is why old vinyl used to get brittle after a while. The modern method is to introduce internal plasticizers which are actually part of the (mostly) PVC molecule; these cannot leach out and keep the vinyl flexible.
PVC is kind of brittle to start with, though it becomes more brittle with age if exposed to sunlight, because UV rays break some of the bonds in the molecules. "Vinyl" (flexible PVC) is flexible because it has additional compounds called "plasticizers" added to it. Over time, these can leach out, again leading to a more rigid and brittle material.
NO. Although you may have plumbers PVC glue, it doesn't work well with flexible PVC like an inflatable. -Better products are Aqua Seal (available in Walmart Sports Dept) or 3M Marine Adhesive.
Carbon, hydrogen, chlorine. If it's flexible, there's probably some oxygen in there as well. Rigid PVC is poly(vinyl chloride), where vinyl chloride is ethene with one of the hydrogens replaced by a chlorine atom. Flexible PVC ... sometimes called simply "vinyl" ... has additives like octyl phthalate (which contains carbon, hydrogen, and oxygen) that keep the polymer swollen and flexible.
