The Kimya PEKK-A 3D filament belongs to the polyaryletherketone family. Polyetherketoneketone (PEKK) is a thermoplastic polymer. PEKK-A is the amorphous form of PEKK, providing ease of printing. This is a material that boasts good mechanical properties and is resistant to high temperatures (<150°C). Produced using KEPSTAN® Arkema, the Kimya PEKK-A 3D filament has been designed for technical applications. It can come into contact with hydrocarbons and fluids, enabling it to be used in multiple business sectors: aerospace, automotive, railways, etc. It has the following properties:
• Temperature resistance
• Flame retardant – eligible to UL94 V0
• Complies with the RoHS and REACH standard
2-year ARMOR warranty.
The PAEK family includes its best known member, PEEK, which differs from PEKK through its ether/ketone ratio. This affects the glass transition temperature of polymer fusion. Compared to PEEK, PEKK offers:
- Enhanced inter-layer adhesion
- Better visual appearance
- Better crystallisation
- Slower crystallisation speed
The two materials provide the same physical-chemical properties.
The PEKK-A from Kimya
The polyetherketoneketone developed by Kimya offers numerous characteristics including high dielectric rigidity and good insulation properties, making it ideal for applications in electrical fields. The PEKK-A can be printed from 350°C and offers excellent temperature resistance (up to 260°C in a continuous process). This hi-tech filament can also be transformed at lower temperatures than other high performance materials, such as PEI or PEEK.
Finally, the PEKK-A provides good chemical resistance and does not degrade in contact with numerous alcohols, acids, hydrocarbons and halogens. However, it is not recommended for use with nitric acid, sulphuric acid or methylene chloride.
