KIMYA PEKK-A Filament - 250 grams, 500 grams, 1kg
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
- Product Dimensions: 20.7 × 20.5 × 6 cm; 0.6 kg
