Product Description
Corrosion Resistant Expanded PTFE Spiral Wound Gasket Tensile Strength 14Mpa
PTFE Gaskets include pure PTFE gasket, expanded PTFE gasket, filled PTFE gasket and PTFE spiral wound gasket.
Pure PTFE Gasket
Manufactured by molding method with PTFE granular resin. PTFE compared with other plastics, has superior properties against chemicals and temperature. Because of such excellent properties, PTFE has wide application as a sealing material.
| Properties | Unit | Result |
|---|---|---|
| Apparent density | g/cm³ | 2.10-2.30 |
| Tensile strength (min) | Mpa | 20-30 |
| Ultimate elongation (min) | % | 200 |
Expanded PTFE Gasket
Cut from expanded PTFE sheet. We can produce any size according to customer requests.
| Compressibility | 12% |
| Recovery | 40% |
| Stress Relaxation | 37% |
| Tensile Strength | 14Mpa |
| Sealing Capability | 0.1m1/hr |
| Temperature | 260 |
| Pressure | 8.3Mpa |
| PH | 0-14 |
Filled PTFE Gasket
Manufactured by molding method with filled PTFE resin. Filled PTFE resin is manufactured by compounding PTFE granular resin with various fillers. Among suitable fillers for compounding with PTFE, glass fiber, carbon fiber, bronze and lubricating materials like graphite, molybdenum disulphide have been widely used in large scale production. PTFE compounds offer advantages over unfilled materials.
| 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
Corrosion resistant and high pressure product. Manufactured by winding metal with PTFE to create PTFE spiral wound gaskets. Available with outer ring, inner ring, or both outer and inner rings.
