PTFE balls can be enhanced with various fillers to improve their mechanical, thermal, or chemical properties for specific applications. Common fillers include glass, carbon, graphite, bronze, and colorants, which can be used individually or blended to achieve desired characteristics. These modifications allow PTFE balls to meet diverse industrial needs, from wear resistance to electrical conductivity.
Key Points Explained:
-
Types of Fillers for PTFE Balls
- Glass Fiber: Improves stiffness and wear resistance, making it suitable for high-load applications.
- Carbon & Graphite: Enhances electrical conductivity and reduces friction, ideal for static-sensitive or low-friction environments.
- Bronze: Increases thermal conductivity and mechanical strength, often used in high-temperature settings.
- Colorants: Primarily for identification or aesthetic purposes without significantly altering mechanical properties.
-
Combination Blends
- Fillers can be mixed (e.g., glass + carbon) to balance multiple properties, such as strength and lubricity.
-
Material Grades
- Virgin PTFE: Pure form, used where chemical inertness is critical.
- Ultra-Modified PTFE: Contains optimized filler ratios for superior performance in extreme conditions.
-
Customization Options
- Hardness, thickness, and filler concentration can be tailored for specific industrial needs.
-
Surface Finishes
- Tumbled (50–63 µin): Standard for general use.
- Machined (32 µin): Smoother finish for precision applications.
-
Sizing & Availability
- Diameters range from 1/8" to 8", with custom production for large quantities.
