CarbonX PEKK-A+CF15: Maximum Mechanical and Thermal Strength

CarbonX PEKK-A+CF15 offers superior properties within the PAEK family. With a glass transition temperature (Tg) of 160°C, a HDT of 150°C, and a melting temperature (Tm) of 305°C, this material is designed for high-temperature applications, continuous mechanical loads, and aggressive chemical environments.

Thanks to its advanced formulation, it features a wide processing window between 360°C and 390°C, with the capability to reach up to 430°C when required by the application. This thermal range ensures printing stability and enhances repeatability in industrial environments. Compared to CF PEEK, CarbonX PEKK-A+CF15 is more accessible, reducing printing issues and improving the dimensional accuracy of final parts.

The addition of 15% high-modulus carbon fiber significantly increases stiffness, dimensional stability, and resistance to thermal deformation, making it an ideal material for tooling, aerospace components, high-performance automotive parts, technical molds, and structural parts under continuous stress.

Chemical Resistance, Low Emissions, and Certified Flame Retardancy

CarbonX PEKK-A+CF15 has inherent flame resistance with a UL94 V-0 rating, a key feature for industries where fire safety is critical. Its formulation also provides low smoke generation and minimal outgassing, essential for electronics, railway, aerospace, and confined-space applications.

The combination of advanced chemical resistance, thermal stability, and certified flame retardancy positions CarbonX PEKK-A+CF15 as a premium solution for high-value industrial additive manufacturing.
