PVC
Also: polyvinyl chloride
PVC is a cheap, heavy boat material used mainly for pool toys and sturdy rafts.
PVC is usually too heavy for packrafts. Exceptions are very robust models like the Kokopelli Recon with 1000-denier reinforced PVC. PVC often contains plasticisers that outgas over time, and it stiffens in the cold. Repairs require different glues than for TPU.
