Thermoplastic
PVC, plasticized (flexible, PVC-P)
Rigid PVC compounded with plasticizers that lower stiffness and glass transition into a soft, ductile material (elongation ~180%) — cable and wire insulation, hoses, flooring, inflatables and medical tubing. Properties swing widely with plasticizer type and loading.
| Property | Value | Source | Method | Conditions | Note |
|---|---|---|---|---|---|
| Density | 1.4 g/cm³ | MakeItFrom.com materials database — typical grade values | — | 23 °C, dry | filler/plasticizer dependent |
| Young's modulus E | 1.4 GPa | MakeItFrom.com materials database — typical grade values | — | 23 °C, dry | a lightly-plasticized grade; heavily-plasticized grades are far softer |
| Tensile strength | 16 MPa | MakeItFrom.com materials database — typical grade values | — | 23 °C, dry | vs ~48 MPa for rigid uPVC |
| Glass transition Tg | 75 °C | MakeItFrom.com materials database — typical grade values | DSC | 23 °C, dry | plasticizer depresses Tg; heavily-plasticized grades drop well below room temperature |
