To overcome these limitations, various fillers such as glass, carbon, graphite, bronze, and others are uniformly blended into ptfe, resulting in filled PTFE compounds with tailored characteristics suitable for seals, bushings, valve seats, gaskets, and wear strips.
Whether your application demands higher strength, lower wear, or enhanced thermal or electrical properties, our range of filled PTFE grades ensures optimal results.
- Wear resistance and mechanical strength
- Dimensional and thermal stability
- Load-bearing capability
- Electrical and thermal conductivity
- Lubrication and friction control
Typically filled with 15% to 35% carbon powder, this grade exhibits:
- Improved wear and load-carrying capacity
- Enhanced thermal and electrical conductivity
- Reduced deformation and creep under stress
- Suitable for seals, bearings, piston rings, and insulating parts in electrical systems
This widely used compound contains 15–25% glass fiber and offers:
- Increased compressive strength and stiffness
- Superior wear resistance with minimal deformation
- Excellent chemical and thermal stability
- Ideal for gaskets, bushings, guide rings, and valves in corrosive or abrasive media
With 5–20% graphite, this formulation provides:
- Exceptional lubricity and dry running performance
- Lower coefficient of friction and smoother motion
- Improved thermal dissipation
- Preferred for rotary seals, dynamic bearings, and valve components
Blended with up to 40% bronze powder, this grade delivers:
- Excellent mechanical strength and wear resistance
- Higher thermal conductivity and dimensional control
- Best suited for high-speed, high-load applications such as wear strips, piston rings, and heavy-duty seals
Specialty-filled grade for critical applications requiring:
- Antimicrobial or conductive performance
- Improved EMI/RFI shielding
- Reliable mechanical and chemical behavior
- Ideal for electronic, labware, or sensitive chemical transfer systems
Combining the strength of glass fiber and the lubricity of molybdenum disulfide (MoS₂):
- Superior wear and load-handling properties
- Lower friction compared to glass-only PTFE
- Used in high-pressure sealing and guide ring applications
Enhanced blend that combines the structure of bronze and the glide of MoS₂:
- Unmatched performance in high-speed, high-load applications
- Excellent thermal conductivity and low friction
- Ideal for piston rings, thrust washers, and dynamic sealing elements
