What are PEEK Granules - DC 4430 G

In modern dental restorations, material choice directly impacts patient comfort and surgical precision. Evonik PEEK DC 4430 G, a peek granule specifically designed for dental applications, features a unique barium sulfate-modified formula that achieves a balance of imaging visibility, biocompatibility, and processing stability. Whether used for digital denture fabrication, image-guided positioning, or prototyping short-term restorations, it is the ideal material for dental manufacturers striving for precision and safety.

1. Material Highlights and Characteristics

Dental imaging visibility

  ・Barium sulfate filling enables PEEK DC 4430G to have excellent X-ray visibility. Doctors can clearly identify the position of the repair piece or guide plate in the image, improving intraoperative accuracy.

Reliable biocompatibility

  ・It has passed the ISO 10993 medical standard test and can be safely used for short-term dental restorations, oral guides and tool components, avoiding tissue irritation and allergic reactions.

Chemical and Sterilization Resistance

  ・It can withstand high-temperature and high-pressure steam sterilization, multiple chemical cleanings, and disinfectant treatments, making it suitable for repeated use in dental labs and clinics.

Отличная размерная стабильность

  ・Its low water absorption rate and stable coefficient of thermal expansion enable it to maintain high precision and consistency in dental precision processing.

2. Typical Dental Application Fields

  ・Dental imaging guide plates and positioning components: They are used as positioning materials in preoperative scanning and digital navigation, and can be precisely developed under X-rays.

  ・Temporary restoration of dental crowns and bridge frame prototypes: used for the trial fitting and structural testing in the early stage of restoration.

  ・Dental drill bit handle and support insert: Resistant to chemicals and heat, capable of withstanding frequent disinfection.

  ・Denture processing rods and digital model materials: Suitable for CNC cutting, hot pressing and digital denture processing procedures.

These applications focus on short-term oral contact and medical auxiliary uses, not long-term implants.

4. Processing and Process Compatibility

PEEK DC 4430 G is supplied as high-viscosity peek granules, suitable for a variety of molding methods:

  ・Литье под давлением: Used for the production of positioning guides, drill handles, and temporary crowns.

  ・Экструзионное формование: Suitable for preparing dental rods, thin sheets and blanks for digital cutting.

  ・CNC and thermoforming processing: It features excellent dimensional stability and surface polishing performance, meeting the requirements of digital dental laboratories.

Its melting temperature (337°C) and high heat distortion temperature (210°C) ensure the thermal stability and surface uniformity during the processing.

5. Innovation and Industry Advantages

Image recognizability

  ・Containing 6% barium sulfate, the material is clearly visible in X-rays and CT scans, and is suitable for dental guides and positioning components.

Адаптивность обработки

  ・Compatible with injection molding, extrusion and CAD/CAM processing, it features stable molding and precise dimensions.

Medical alternative

  ・As a non-metallic material, it can replace some metal dental components and has both strength and biocompatibility.

6. Customer Feedback

The visibility of PEEK DC 4430G greatly improves the accuracy of the image guide plate and makes the surgical simulation process more efficient.

"The peek granules batch we purchased through Juyuan is stable, with consistent molding fluidity, and the surface is smooth and bubble-free after CNC machining."

7. FAQ

Q1: Can PEEK DC 4430 G be used for permanent implants?

A: Not recommended. It is intended for dental prosthetic aids and short-term contact components, such as guides and temporary crowns, but not for long-term implants.

Q2: Can it be repeatedly sterilized?

A: Yes. The material can withstand multiple 134°C steam sterilizations or chemical disinfection with stable performance.

Q3: Can it be used in digital denture fabrication?

A: Absolutely. PEEK DC 4430 G can be used as a raw material for processing digital dental models, denture blanks, and restoration guides.
