III. Application and Process Compatibility

1. Processing Characteristics

Ketron® 1000 PEEK pellets offer a combination of flowability, toughness, and dimensional stability, making them suitable for injection molding, extrusion, and precision machining.

The unfilled system ensures more uniform melt flow, resulting in smooth surfaces and balanced stress distribution after molding, making the molded parts less susceptible to cracking or warping.

The low water absorption (24-hour water absorption of only 0.06%) ensures dimensional accuracy and sealing reliability in humid or high-temperature environments.

Therefore, it is often selected for components requiring long-term airtightness and chemical resistance.

💡 Processing Recommendation: Maintaining mold temperature between 170–200°C improves part crystallinity and mechanical strength, making it suitable for molding demanding sealing components.

2. Typical Applications

Ketron® 1000 PEEK is widely used in a variety of high-end manufacturing fields, particularly excelling in the following applications:

  ・Hydraulic and pneumatic system seals – maintain stable dimensions and low wear rates even after long-term operation in high-pressure fluids.

  ・Valve seats and pump bushings for chemical equipment – ​​exhibit excellent chemical inertness and resistance to acid, alkali, and solvent corrosion.

  ・Food processing machinery contact components – certified for food contact, ensuring safety and no leaching, meeting hygienic standards.

  ・Electrical insulation sealing components – combining insulation and heat resistance, suitable for electrical packaging and sensor housings.

With its combination of pure resin, high toughness, and low water absorption, Ketron® 1000 PEEK is an ideal material choice for seals, valve seats, sliding rings, and precision insulation components.

Whether used in food processing machinery, chemical fluid systems, aviation, or clean manufacturing equipment, it achieves a precise balance between heat resistance, wear resistance, and chemical stability.
