Key Features & Advantages

Exceptional Chemical Resistance: Inert to most chemical solvents, acids, and alkalis
Superior Lubrication: Low coefficient of friction for smooth operation
Non-Stick Properties: Minimal surface tension prevents material adhesion
Wide Temperature Tolerance: Maintains performance from -200°C to 350°C
Excellent Mechanical Strength: 5% elongation retention even at -196°C
Weather Resistant: Superior aging resistance and long service life
Physiologically Inert: Suitable for specialized applications including medical components

Functional Applications

These PTFE backup rings serve as critical supporting components in various industrial systems:

Corrosion-resistant sealing systems
Support slides and guide rails
Electrical insulation components
Shaft seal protection
Static sealing applications with O-rings

Installation & Usage

Designed for installation in grooves alongside elastomeric sealing elements, preferably with corresponding O-rings in static applications. The tight fit in the housing prevents extrusion of pressurized sealing elements into sealing gaps.
