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.
