Expanded PTFE (EPTFE) gaskets are engineered for demanding industrial applications, offering a unique combination of mechanical resilience, chemical inertness, and thermal stability. These gaskets excel in sealing irregular surfaces while maintaining integrity under extreme pressures and temperatures, making them indispensable for chemical processing, oil/gas, and pharmaceutical industries. Their non-stick properties and electrical insulation further broaden their utility across diverse operational environments.
Key Points Explained:
-
Chemical Resistance
- Withstand virtually all acids, bases, solvents (pH 0-14) including:
- Hydrochloric/sulfuric acids
- Caustic soda
- Hydrocarbons like benzene
- Ideal for chemical plants where ptfe gasket prevent leakage in aggressive media transfers.
- Withstand virtually all acids, bases, solvents (pH 0-14) including:
-
Temperature Tolerance
- Operate from cryogenic (-40°F/-40°C) to 600°F (315°C)
- Outperform rubber gaskets in steam applications
- Thermal cycling stability minimizes flange retorquing needs
-
Pressure Performance
- Handle 3,000+ psi in optimized flange designs
- Compensate for surface irregularities through:
- 70-80% compressibility
- Memory retention after compression
-
Mechanical Properties
- Creep/cold flow resistance maintains bolt load
- 5x more flexible than standard PTFE
- Protect fragile flanges (glass-lined pipes, thin metals)
-
Secondary Benefits
- FDA/USP Class VI compliant for food/pharma
- Dielectric strength >19kV/mm
- Zero VOC emissions
For critical sealing scenarios involving thermal shocks or corrosive chemicals, EPTFE's microporous structure provides reliable long-term performance where traditional materials fail. Their adaptability to imperfect flange conditions reduces installation precision requirements, lowering total cost of ownership.
