| Ideal Applications | Seals, valves, insulators, pumps | Cryogenic seals, pharma, gas systems | Aerospace, dry-run seals, vacuum systems |
In-Depth Material Insights
PEEK – Heat + Strength + Versatility
• Pros: Excellent dimensional stability, fatigue resistance, and wear performance under continuous stress.
• Cons: Less effective at ultra-low cryogenic temperatures.
• Common Use: High-pressure valve seats, compressor seals, bearing cages.
• Best Fit For: Applications requiring a balance of mechanical performance and chemical resistance in high-heat environments.
PCTFE – Cold Stability + Chemical Resistance
• Pros: Near-zero moisture absorption, excellent dimensional stability, non-flammable.
• Cons: Not ideal for high-load or high-temperature dynamic applications.
• Common Use: Cryogenic seals, oxygen systems, pharma-grade valves.
• Best Fit For: Static sealing under ultra-cold conditions and corrosive environments.
Vespel® – Ultra High Temp + Mechanical Load Capacity
• Pros: Withstands thermal shock, ideal for vacuum and radiation environments, and machinable to tight tolerances.
• Cons: Higher cost, requires precision machining.
• Common Use: Aerospace valve seats, jet engine components, high-speed dry-running seals.
• Best Fit For: Applications demanding long-term thermal and structural performance under extreme pressure or heat.
