化学処理におけるPTFEシールの工業用途
Polytetrafluoroethylene (PTFE) seals are widely used in chemical processing industries due to their exceptional chemical resistance, low friction, and high-temperature tolerance. Proper sealing is critical in chemical systems to prevent leakage, ensure operational safety, and maintain equipment efficiency. 1. Why PTFE Seals Are Preferred in Chemical Processing PTFE offers several advantages over traditional elastomer seals: • Chemical Inertness – Resistant to acids, alkalis, solvents, and aggressive chemicals• Wide Temperature Range – Operates from -200°C to 260°C depending on design• Low Friction Coefficient – Reduces wear and energy loss in dynamic applications• Non-Contaminating – Ideal for high-purity processes and hygienic systems• Long Service Life – Less prone to swelling, deformation, or […]
