Description

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.

PEEK

Overview

A premier polymer – one of the highest performance thermoplastics ever invented.

PEEK is an ultra-performance filament, ideal for the most demanding functions in Aerospace, Automotive and Electronic applications. This is possible as it has incredible mechanical properties, excellent strength and durability, resistance to corrosion and temperatures, and flame retardancy. It can withstand boiling water and steam.

Printing with this material is very difficult and requires a significant amount of experience in 3D printing. A high quality or heavily modified printer is mandatory.
