When to Choose Pure PEEK and filled PEEK
| Your Core Requirement | Recommended Grade | Key Benefits |
|---|---|---|
| Electrical Insulation | Pure PEEK | High dielectric strength with no conductive additives; ideal for isolators. |
| High Purity / Low Contamination | Pure PEEK | FDA compliant and biocompatible with minimal outgassing for cleanrooms. |
| High Stiffness & Strength | GF30 (Glass Fiber) | 30% glass fiber reinforcement for superior rigidity and dimensional stability. |
| Maximum Strength / Lightweight | CF30 (Carbon Fiber) | 30% carbon fiber for the highest strength-to-weight ratio and fatigue resistance. |
| Low Friction / High Wear | Bearing Grade | Formulated with PTFE/Graphite/Carbon for high-speed, non-lubricated parts. |
| EMI Shielding / Conductivity | CF30 (Carbon Fiber) | Carbon fibers provide electrical conductivity to prevent static or block EMI. |

FAQs
Pure PEEK (Polyetheretherketone) is a high-performance semi-crystalline engineering thermoplastic known for its exceptional mechanical strength, chemical resistance, and high-temperature stability. It contains 100% PEEK resin without any added reinforcements or fillers.
Yes. These terms are used interchangeably. “Virgin” or “Unfilled” signifies that the material is in its natural state, without the addition of glass fiber, carbon fiber, or lubricants.
Pure PEEK has a continuous service temperature of 260°C (500°F). It also retains its excellent mechanical properties even in short-term excursions up to 300°C.
Yes. Pure PEEK is naturally biocompatible and meets FDA (Food and Drug Administration) requirements for food contact.
Yes. Pure PEEK is an excellent electrical insulator with a high dielectric strength (typically 18-20 kV/mm).
Choose Pure PEEK for high purity, electrical insulation, or FDA compliance. Choose CF30 if you need maximum stiffness and load-bearing capacity.
Choose Pure PEEK for better ductility and chemical purity. Choose GF30 if you need higher dimensional stability at elevated temperatures.
Absolutely. Pure PEEK has excellent machinability and can be precision machined to very tight tolerances using standard CNC equipment.
We offer standard sizes: Rods (Dia 5mm-200mm), Sheets (Thickness 1mm-100mm), and custom tubes.
Yes. Its high purity and low outgassing make it ideal for medical implants and semiconductor wafer handling.
Standard items ship within 24-48 hours. Custom machining typical lead time is 5-10 business days.
Yes. We provide Material Certificates (COA), SGS Test Reports, and FDA/RoHS statements with every shipment.
