Kimya PEKK-A 3D Filament (KEPSTAN®)

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 KIMYA warranty.
