What is PEEK Raw Material

ColorRx® PEEK-3000RX is a peek raw material for the medical industry under AURUMICHEM. This material demonstrates stable and reliable performance in the field of high-standard medical devices due to its excellent biocompatibility, chemical corrosion resistance and radiation resistance. With its balanced mechanical strength and thermal stability, it has become an ideal material choice for the manufacturing of disposable medical supplies, implant-grade components and surgical auxiliary instruments.

1. Overview of material properties

ColorRx® PEEK-3000RX is a high-purity system of unfilled grade PEEK, produced through a precisely controlled polymerization process to ensure batch-to-batch consistency and low precipitation characteristics. Its main features include:

  ・Excellent biocompatibility: Complies with multiple biological testing standards and can be in long-term contact with human tissues or body fluids.

  ・Excellent chemical stability: Resistant to acids, alkalis, alcohol and various disinfectants;

  ・Gamma-ray and ethylene oxide sterilization resistance: It can maintain mechanical and appearance properties during multiple sterilization cycles.

  ・Medium to high flow characteristics: Melt index (MI) 36 g/10min (400°C/2.16kg), facilitating micro-injection molding of complex medical devices;

  ・High thermal stability: The heat distortion temperature reaches 320°F (approximately 160°C), making it suitable for high-temperature operations and sterilization environments.

2. Performance analysis

ColorRx® PEEK-3000RX maintains material purity while still featuring excellent mechanical balance:

These performance data indicate that the peek raw material achieves a good balance between flexibility and rigidity, and is highly suitable for medical device structural components that require impact resistance and anti-deformation.

3. Processing suggestions

ColorRx® PEEK-3000RX is mainly produced by injection molding. Its high melt fluidity makes it suitable for multi-cavity molds and precision injection molding production. Recommended processing conditions

  ・Barrel temperature: 370-400°C

  ・Mold temperature: 160-200°C

  ・Drying conditions: 3 to 4 hours at 150°C

  ・Recommended Screw Speed: Medium to prevent shear degradation

in mold design, the low shrinkage rate of the material (0.014-0.016 in/in) should be taken into account to ensure dimensional accuracy and surface flatness.

4. Application performance in the medical field

Thanks to its chemical inertness and stability, ColorRx® PEEK-3000RX has been widely used in:

  ・Disposable medical devices (such as catheter connectors, fixtures, and connecting parts);

  ・Reusable sterilizable medical care supplies;

  ・Surgical support instruments, joint components of medical robots;

  ・Temporary implants or non-long-term contact medical components.

Its gamma-ray resistance performance enables this peek raw material to adapt to the diverse sterilization process requirements in the modern medical industry, including irradiation, steam and ethylene oxide.

5. Market Trends and Material advantages

As global medical devices move towards "lightweight, precision and repeatable sterilization", PEEK materials are gradually replacing traditional metals and engineering plastics such as PPSU and PEI.

ColorRx® PEEK-3000RX, with its stable physical properties and excellent flow processability, offers medical device manufacturers more flexible design space and a higher safety factor.

For the medical-grade plastic supply chain, choosing compliant, stable and traceable peek raw material has become the core standard for international procurement.
