PEEK (Polyetheretherketone) is a high-performance engineering thermoplastic widely specified in packaging equipment for its exceptional mechanical strength, thermal stability, and chemical resistance. At QuikCNC, we precision-machine PEEK components for pharmaceutical packaging lines, food processing equipment, and demanding wear applications where standard plastics would fail prematurely.
🔥 Key Properties
- Tensile Strength: 90-100 MPa — among the strongest of all thermoplastics
- Continuous Service Temperature: Up to 260°C (500°F)
- Chemical Resistance: Excellent against acids, bases, and organic solvents
- Wear Resistance: Outstanding in sliding and abrasive environments
- FDA Compliance: PEEK is FDA-compliant for food contact applications
- Sterilization: Withstands autoclave, gamma, and ethylene oxide sterilization
⚙️ Common Applications in Packaging
- Pump rotors, impellers, and housings in liquid filling machines
- Valve seats and seals for pneumatic and hydraulic systems
- Wear rings and bushing for high-speed rotating shafts
- Guide rails and bearing cages in cartoning machines
- Piston rings and seals for filling nozzles
- Hot gripper components for heat-sealing stations
- Structural brackets requiring high strength-to-weight ratio
