PTFE balls, known for their exceptional chemical resistance, low friction, and non-stick properties, can be manufactured from various PTFE-based materials. These include virgin PTFE, modified PTFE, and compounded PTFE with fillers like stainless steel, glass, carbon, or bronze. The choice of material depends on the desired mechanical, thermal, or electrical properties for specific applications.
Key Points Explained:
-
Virgin Grade PTFE
- Pure PTFE without additives, offering the highest chemical resistance and lowest friction.
- Ideal for applications requiring uncompromised non-stick properties or ultra-pure environments.
- Example: PTFE bushings and seals where contamination must be minimized.
-
Modified PTFE (e.g., Teflon NXT 85)
- Enhanced with proprietary additives to improve wear resistance or reduce cold flow.
- Suitable for dynamic applications where standard PTFE may deform over time.
-
Stainless Steel-Filled PTFE (50% 316 Stainless Steel, 50% PTFE)
- Combines PTFE’s lubricity with stainless steel’s mechanical strength.
- Used in high-load or abrasive environments, such as bearings or valve components.
- The stainless steel filler improves thermal conductivity and reduces wear.
-
Glass-Filled PTFE (15% or 25% Glass Fibers)
- Glass fibers reinforce the PTFE matrix, increasing stiffness and creep resistance.
- Common in industrial seals or gaskets requiring dimensional stability under pressure.
- The 25% variant offers higher rigidity than the 15% version.
-
Hybrid Fillers (10% Glass + 10% Carbon-Filled PTFE)
- Balances glass’s strength with carbon’s electrical conductivity.
- Applied in electrical insulation or sliding contacts where moderate conductivity is needed.
-
Bronze-Filled PTFE
- Bronze particles enhance thermal conductivity and load-bearing capacity.
- Often used in high-temperature bushings or thrust washers.
-
Custom PTFE Compounds
- Tailored formulations (e.g., aramid fiber or ceramic-filled) address niche requirements like extreme temperatures or EMI shielding.
- Available upon request for specialized engineering solutions.
