Filled PTFE (Polytetrafluoroethylene) is a modified version of pure PTFE, enhanced with various fillers to improve its mechanical and thermal properties. Common fillers include glass fibers, carbon, graphite, bronze, or ceramics, which increase wear resistance, reduce creep, and enhance load-bearing capacity while retaining PTFE’s inherent chemical inertness and low friction.

Key Features:

• Enhanced Durability: Better wear resistance and reduced deformation under load.
• Low Friction: Maintains excellent non-stick and self-lubricating properties.
• Chemical Resistance: Resists most corrosive chemicals and solvents.
• Wide Temperature Range: Performs well from -200°C to +260°C.

Applications:
Used in seals, bearings, gaskets, and sliding components across industries like automotive, aerospace, and chemical processing.

Filled PTFE combines the best of PTFE with added strength for demanding environments.
