PTFE vs. X-ECOPUR Seals: Polyurethane the better alternative?
When it comes to sealing solutions, choosing the right material is crucial for performance and longevity. Let's compare two popular options: PTFE and X-ECOPUR.
PTFE (Polytetrafluoroethylene):
🔹 Chemical Resistance: Outstanding, compatible with a wide range of chemicals.
🔹 Low Friction: Excellent, ideal for applications requiring minimal friction.
🔹 Wear Resistance: Good, but can be outperformed by advanced polyurethanes in some conditions.
X-ECOPUR (Thermoplastic Polyurethane):
🔹 Extrusion Resistance: Superior, allowing higher pressure applications.
🔹 Abrasion Resistance: Excellent, providing longer service life in dynamic applications.
🔹 Hydrolysis Resistance: X-ECOPUR H available for permanent hot water contact up to 90°C.
🔹 Regulation: Totally PFAS-free
Choosing between PTFE and X-ECOPUR depends on your specific application needs. For exposure to agressive chemicals, PTFE is a strong contender. For high pressure and abrasion resistance in heavy duty applications, X-ECOPUR is the an excellent alternative that is PFAS-free on top.
