- Apparent density: 2.10-2.30 g/cm3
- Size: customized
Expanded PTFE Gasket
Cut from expanded PTFE sheet. Various size is available
- Temperature Range: up to 260 °C
- Tensile Strength: 14 Mpa
- Compressibility: 12%
- Sealing Capability: 0.1ml/hr
- Size: customized
Filled PTFE Gasket
Manufactured by molding method with filled PTFE resin.
Different fillings determines different performance, as is listed below:
| Filled compound and Content by wt | Tensile strength MPa(min) | Ultimate strength %(min) | Compressive strength MPa(min) |
| 20% glass fiber | 10 | 120 | 16 |
| 25% glass fiber | 10 | 100 | 16 |
| 20% glass fiber 5% graphite | 10 | 120 | 16 |
| 60% Bronze | 10 | 80 | 20 |
| 15% carbon fiber | 11 | 130 | 16 |
| 24% Bronze 12% glass fiber 6% graphite | 9 | 100 | 16 |
| 15% glass fiber 10% polyimide 5% graphite | 10 | 120 | 16.7 |
PTFE Spiral Wound Gasket
By winding metal with PTFE gasket. It could fix the outer ring or inner ring. PTFE spiral wound gasket is corrosion resistant as well as high pressure resistant.
