The ever-increasing demand for high-tech products ensures a worldwide increase in demand for high-precision PTFE skiving ultra-thin to heavy-gauge PTFE engineered for critical sealing applications.
Precision Without Compromise
Durlon® is proud to introduce our new Precision Skiving Machine, engineered to deliver exceptional accuracy, repeatability, and material uniformity across ultra-thin to heavy-gauge skived PTFE sheet. Our Programmable Logic Controlled (PLC) system produces thicknesses from 0.03 mm (0.002″) up to 8.0 mm (0.31″), ensuring spec-level precision for the most demanding applications.
Whether you’re sealing micro-scale instrumentation or compensating for uneven flange surfaces in heavy industrial systems, Durlon’s enhanced skiving capability ensures consistency, reliability, and improved sealing performance.
Why Digital Skiving Matters
- Thickness accuracy and tolerance control
- Uniformity across full sheet width
- Material efficiency and yield
- Lead times and production agility
- Waste reduction and sustainability
These enhancements translate directly into:
- More reliable sealing performance
- Better fit in tight tolerances and complex assemblies
- Confidence in repeatability across multiple production runs
Thickness Capabilities and Application Guidance
~0.03 mm (0.002″)
When to choose ultra-thin: Tight sealing clearances, low bolt load environments, precision stack-ups, membrane layers, or applications requiring inert barrier films rather than compressive gasket cushioning.
Application Areas:
| Industry | Typical Uses | Why This Thickness Works |
|---|---|---|
| Semiconductor, Electronics | Vacuum tools, wafer handling, CVD/etch chamber seals, viewport seals, micro-gas line interfaces | Minimizes particle generation and maintains critical vacuum tolerances |
| Medical Devices, Diagnostics | Microfluidic manifold seals, pump and valve diaphragm face layers, isolation membranes | Thin PTFE provides chemical inertness without adding stiffness |
| Aerospace, Avionics | Fuel and oxidizer line seals, bleed-air connectors, instrument enclosures | Maintains exact stack-up tolerances and reduces weight |
| Laboratory Equipment | HPLC/GC fittings, syringe pumps, sampling interfaces | Prevents cold-flow intrusion into precision fluid pathways |
| Food and Beverage, Pharmaceutical | Sanitary tri-clamp face liners, sight-glass seals | Smooth, cleanable sealing surface while preserving ferrule engagement |
| Precision Hydraulics, Pneumatics | Spool valve seals, regulator plates, manifold gaskets | Supports low bolt loads in tight mechanical envelopes |
| Energy/Battery, Fuel Cell Systems | Stack perimeter gaskets, sensor isolation film layers | Maintains compression requirements and ionic flow pathways |
General Purpose Skived PTFE
~0.5–2.0 mm (0.020–0.080″)
Best for: Light-to-moderate flange loads, instrument housings, valves, pumps, and compressor sealing.
| Industry | Applications |
|---|---|
| Industrial Valves and Pumps | Bonnet/cap seals, pump casing gaskets, meter flange interfaces |
| HVAC/Refrigeration and Compressors | Plate seals, cover gaskets, oil sight-glass seals |
| Water/Wastewater Systems | Instrument tees, actuator housings, small ANSI/ISO flanges |
| Heavy Machinery | Fuel system seals, EGR systems, chemical media containment |
Thick Skived PTFE
2.0-8.0 mm (0.080–0.315″)
When thickness is required: To compensate for inconsistent flange surfaces.
| Industry | Applications | Why Thick PTFE Helps |
|---|---|---|
| Chemical Processing, Petrochemical | Aggressive media flanges, glass-lined reactors, heat exchanger covers | Thickness compensates for enamel/glass irregularities and chemical exposure |
| Pulp and Paper, Mining | Large process flanges, stock chests, agitators | Withstands abrasive and caustic environments |
| Food and Beverage, Pharma (CIP/SIP) | Sanitary tank lids, manways, large tri-clamp assemblies | Supports compliant sealing during thermal cycling |
| Power Generation, Renewables | Dosing systems, scrubbers, geothermal brine lines | Maintains sealing integrity across variable conditions |
