Performance Advantages
• High Lubrication: Solid material with extremely low coefficient of friction
• Non-Sticking Properties: Minimal surface tension prevents adhesion
• Chemical Resistance: Inert to most solvents, acids, alkalis, and organic compounds
• Temperature Stability: Maintains 5% elongation even at -196°C
• Weather Resistance: Exceptional aging life among plastic materials
• Physiological Inertness: Suitable for medical applications including implants
Application Scenarios
Ideal for use with O-rings in high-pressure systems, low-hardness O-ring materials, radial sealing gap compensation, and both internal/external sealing applications. Supports reciprocating and rotating movements while accommodating significant temperature fluctuations in static and dynamic environments.
Industry Applications
Automotive systems, electrical equipment, industrial machinery, and specialized sealing applications requiring reliable performance under extreme conditions.
