| Grade / EN | Polymer | Pigment | Resin source | Type S | Type P |
|---|---|---|---|---|---|
| PTFE PTFE | Unfilled PTFE | Up to 1.5% by mass | Virgin, reprocessed or recycled, as designated | Dimensionally stabilized | As processed |
Material classification for unfilled PTFE; pigments are limited to 1.5% by mass.
| Grade / EN | Class | Tensile strength (MPa) | Elongation at break (%) |
|---|---|---|---|
| PTFE PTFE | Property class 1 | ≥25 | ≥280 |
| PTFE PTFE | Property class 2 | 20 ≤ Rm < 25 | 200 ≤ A < 280 |
| PTFE PTFE | Property class 3 | 15 ≤ Rm < 20 | 150 ≤ A < 200 |
| PTFE PTFE | Property class 4 | 10 ≤ Rm < 15 | 75 ≤ A < 150 |
| PTFE PTFE | Property class 5 | <10 | <75 |
Density: 2.13–2.19 g/cm³; reprocessed resin and blends: 2.14–2.23 g/cm³. Type S dimensional change is limited to 0.5%. Hardness requirements, where specimen geometry permits measurement: ball indentation above 23 MPa or Shore D above 54.
