What is PEEK Raw Material

Ketaspire™ KT 820 is a flame-retardant PEEK raw material from Solvay and is a member of the high-purity polyetheretherketone system. It combines thermal stability, radiation sterilization resistance and structural strength. It can maintain good mechanical integrity and dimensional stability even in extreme environments, making it particularly suitable for engineering applications that require long-term heat exposure and high-intensity operations.

One of its features lies in the V-0 flame retardant grade (thickness ≥1.5mm), and it can still reach V-1 under thin-walled conditions. While meeting the requirements of lightweight structure, it ensures the fire safety of the parts.

01 | Main Performance and Structural Characteristics

Ketaspire™ KT 820 adopts a modified PEEK-FR formula, with an efficient flame retardant system and lubricating additives introduced internally, achieving a balance among mechanical, thermal and electrical properties of the material.

  ・Outstanding high-temperature resistance: The long-term operating temperature can reach 260°C, and RTI (electrical/structural) demonstrates stable resistance to thermal aging.

  ・Outstanding flame retardant performance: With an oxygen index of 37%, it still achieves V-0 flame retardancy even in a halogen-free formula, meeting the safety standards for electronic and medical devices.

  ・Multi-sterilization compatibility: It can withstand steam, high pressure, ethylene oxide, gamma rays and electron beam sterilization without performance degradation.

  ・Combining mechanical strength with toughness: The tensile strength can reach up to 124 MPa, the elongation at break exceeds 200%, while maintaining a good fatigue life.

  ・Stable electrical insulation: Dielectric constant 3.1, volume resistivity as high as 2.6×10¹⁶ Ω·cm, suitable for use in precision electrical components.

  ・Dimensional stability and chemical corrosion resistance: Low water absorption rate (0.5%) and low linear expansion coefficient (4.3×10⁻⁵ cm/cm/℃) ensure that the parts do not deform during thermal cycling.

02 | Typical Application Fields

With its unique heat resistance and sterilization performance, Ketaspire™ KT 820 is widely used in:

  ・Medical and nursing equipment: surgical instrument handles, dental applications, implant device housings, reusable sterilizable components.

  ・In the field of electronics and electrical engineering: connectors, coil bobbins, precision insulating components.

  ・Aviation and automotive industry: lightweight heat-resistant structural components, fuel system parts, sealing rings, pump and valve accessories.

  ・Industry and Energy: Oil and gas sealing components, high-temperature wear-resistant gears and pump body parts.

04 | Process Compatibility and Processing Suggestions

The particle form of Ketaspire™ KT 820 is convenient for a variety of thermal processing techniques:

  ・Injection molding: Suitable for batch manufacturing of high-precision components, the mold temperature needs to be controlled at approximately 180°C.

  ・Extrusion molding: It can be made into films, pipes and profiles. The melting temperature is approximately 340°C.

  ・Hot press forming: Suitable for the preparation of medical films or industrial separators.

Thanks to its excellent fluidity and thermal stability, the material maintains uniform molding at high shear rates, reducing problems such as bubbles, stress concentration and dimensional deviations in the workpiece.

05 | Industry Performance and Compliance Standards

  ・Passed UL94 V-0/V-1 flame retardant certification.

  ・Complies with UL 746B long-term thermal aging grade (RTI 260°C).

  ・The electrical, mechanical and thermal performance data all comply with the ASTM/IEC international standard test methods.

  ・Medical-grade specifications are available to meet the requirements of biocompatibility and multiple disinfection uses.

These characteristics enable it to demonstrate stable expected lifespan and reliability in highly demanding medical devices and industrial systems.
