Virgin PEEK Resin (PEEK 1000 / Natural Grade)
Virgin PEEK resin offers the highest purity and mechanical integrity, ideal for customers who require base polymer for compounding or direct molding. It provides excellent chemical resistance, low moisture absorption, and thermal stability up to 250 °C.
Glass Fiber Reinforced PEEK (PEEK Gf30 / Gf20)
Glass-filled PEEK resin enhances stiffness and dimensional stability while maintaining high temperature strength. It is suitable for molded parts that need rigidity and creep resistance, such as compressor or pump components
Carbon Fiber Reinforced PEEK (PEEK Cf30 / Cf20 / Ca30)
Carbon-filled PEEK resin delivers outstanding mechanical strength and lower thermal expansion. It is recommended for applications requiring lightweight stability and excellent wear performance.
Esd / Conductive PEEK Compounds
Our conductive PEEK materials incorporate carbon black or fiber reinforcement to achieve stable electrical conductivity. These materials are ideal for electronic, semiconductor, and static-control equipment manufacturing.
Ceramic & PTFE-Filled PEEK
Ceramic-filled and PTFE-modified PEEK resins offer a combination of low friction, high wear resistance, and thermal stability. They are widely used by compounders and molders to produce components with extended service life.

Processing Guidelines
For optimal performance, PEEK resin should be dried at 150 °C for 3–4 hours before molding.
Recommended processing temperatures are:
-
Injection Molding: 360–400 °C (barrel)
-
Extrusion: 350–380 °C
-
Mold Temperature: 160–200 °C
Proper temperature control ensures full crystallization and maximum mechanical properties of PEEK polymer products.
FAQ of PEEK Material
What are the key benefits of PEEK material?
The main benefits of PEEK material include high temperature resistance, excellent chemical stability, strong mechanical performance, wear resistance, and low moisture absorption. These properties help support reliable part performance in harsh environments.
What products can be made from PEEK material?
PEEK material can be processed into pellets, powder, sheet, rod, film, and finished machined parts. It is used for seals, bearings, valve parts, electrical components, insulation parts, medical components, and precision industrial parts.
How do I select the right PEEK grade?
Selecting the right PEEK grade depends on the working temperature, mechanical load, chemical exposure, wear conditions, and processing method. Unfilled PEEK is suitable for general engineering use, while reinforced grades are often chosen for higher strength, stiffness, or wear resistance.
Is PEEK material better than standard engineering plastics for harsh environments?
In many high-performance applications, yes. PEEK material offers better heat resistance, chemical resistance, and long-term dimensional stability than many standard engineering plastics, making it a strong choice for critical industrial parts.
Is PEEK material easy to machine and process?
PEEK material can be machined into high-precision parts, but it requires proper tooling and process control because it is a high-performance engineering plastic. It can also be processed through extrusion, injection molding, and compression molding, depending on the grade and product form.
What is the difference between unfilled PEEK and filled PEEK?
Unfilled PEEK offers a balanced combination of toughness, chemical resistance, and processability. Filled PEEK, such as glass-filled PEEK or carbon-filled PEEK, is designed to improve specific properties like stiffness, dimensional stability, strength, or wear resistance. The right choice depends on the final application and operating conditions.
Does PEEK material absorb water?
PEEK material has low moisture absorption compared with many other engineering plastics. This helps it maintain dimensional stability and consistent mechanical performance, which is important for precision components and applications exposed to changing humidity or moisture.
Why is PEEK material used in high-value industrial applications?
PEEK material is often chosen for high-value industrial applications because it combines multiple performance advantages in one material, including heat resistance, chemical resistance, wear resistance, strength, and long-term stability. This makes it suitable for critical parts where failure is costly and material performance directly affects product reliability.
