Differences and Applications of Different Grades of PEEK Rods

Unfilled PEEK Rods (Pure PEEK)

Unfilled PEEK Rods (Pure PEEK)

Properties: This is the most basic grade of PEEK rods, without any additives. It offers the highest toughness and best impact resistance in the PEEK family. It also has extremely high purity, meeting FDA and other certification standards.

Applications: Commonly used in parts requiring high purity and toughness, such as medical implants, food processing machine components, and precision parts that need to absorb impacts.

CF30 PEEK Rods (30% Carbon Fiber Reinforced PEEK)

CF30 PEEK Rods (30% Carbon Fiber Reinforced PEEK)

Properties: Contains 30% carbon fiber, significantly enhancing the material's strength, rigidity, and creep resistance. The addition of carbon fiber also provides conductivity, allowing it to dissipate static electricity.

Applications: Suitable for components requiring high load capacity, high rigidity, and static dissipation, such as aerospace structural components, semiconductor equipment fixtures, and test probes.

GF30 PEEK Rods (30% Glass Fiber Reinforced PEEK)

GF30 PEEK Rods (30% Glass Fiber Reinforced PEEK)

Properties: Contains 30% glass fiber, providing very high rigidity and heat deflection temperature, allowing it to maintain its shape stability even at high temperatures. However, glass fiber also makes the material more brittle and abrasive.

Applications: Primarily used for structural components that need to withstand high loads and high temperatures, such as industrial gears, pump and valve components, and electrical insulation parts.

Bearing Grade PEEK Rods

Bearing Grade PEEK Rods

Properties: Typically made from a combination of carbon fiber, graphite, and PTFE or other fillers. This combination gives the material an extremely low friction coefficient and excellent wear resistance, providing superior self-lubricating properties.

Applications: Specifically designed for sliding and friction applications, such as manufacturing bushings, bearings, seals, and piston rings.

Note: The weight per meter is based on the density of unfilled PEEK (approximately 1.31 g/cm³) for reference only. The actual weight of different filled grades of PEEK rods may vary due to differences in their densities (e.g., GF30 density is approximately 1.51 g/cm³, CF30 is approximately 1.41 g/cm³, and Bearing Grade is approximately 1.44 g/cm³).
