Premium PTFE Expanded Gasket & ePTFE Gasket
An expanded PTFE gasket provides a highly conformable, chemically inert sealing solution for flanges and process equipment. Its soft, fiber-free structure easily adapts to surface irregularities, delivering long-lasting, leak-tight performance across a wide range of chemicals, temperatures, and pressures.

As a specialized expanded ptfe manufacturer, Hebei Xinda offers high-quality ptfe expanded gaskets designed for demanding industrial environments. Our eptfe gasket is made from 100% virgin PTFE, utilizing a unique expansion process that creates a highly fibrous, multidirectional structure. This ensures our ptfe gasket products provide exceptional sealing performance even on worn or irregular flanges.
PTFE Gasket Data Sheet
| Test Item | Unit | Target |
| Density | g/cm³ | 2.1-2.3 |
| Tensile Strength | Mpa | ≥15.0 |
| Ultimate Elongation | % | ≥150 |
Because there are many types of PTFE gaskets, specific production is carried out according to requirements.
Universal Chemical Resistance: Both our ptfe expanded gasket and standard ptfe gasket are compatible with almost all aggressive media.
Material Grades: We offer customized ptfe material formulations including 100% virgin and various filled grades to meet specific friction and wear requirements.
Technical Advantages
High-Performance PTFE Expanded Gasket (ePTFE Gasket)
- Superior Compressibility: Our ptfe expanded gasket conforms easily to rough or damaged flange surfaces, requiring lower bolt torque.
- Zero Cold Flow: Unlike standard ptfe gaskets, our ePTFE structure resists creep and cold flow, ensuring long-term seal integrity.
- Universal Chemical Resistance: Compatible with PH 0-14, making it the ideal ptfe material for aggressive chemical media.
- High Temperature Stability: Reliable performance from -240°C to +260°C.
Best For: Irregular, fragile, or worn flanges (Glass-lined, Plastic).
Durable Industrial PTFE Gasket (Standard PTFE)
As a leading ptfe gasket manufacturer, we also provide a full range of traditional PTFE gaskets cut from high-density molded or skived sheets.
Types Available: Pure Virgin PTFE gasket, Carbon-filled PTFE, and Glass-fiber filled PTFE gasket.
Best For: Standard flat flanges in petroleum, metallurgy, and general chemical processing.
Key Benefit: Exceptional chemical inertness and high cost-effectiveness for mass industrial applications.
